The construction operation of oil and gas field well sites has the risks of flammability and explosiveness of mediums such as oil, gas and the like, and potential safety hazards such as high-voltage electricity utilization and the like. According to the data statistics of China institute of safety and production science, 90% of safety accidents occur in an operation site, and 88% of site accidents are caused by well site personnel, so that the safety management of the well site personnel is an important work of an oil and gas field well site, and strict personnel safety management measures are required to be implemented in order to ensure that various engineering projects of the well site can be completed safely and smoothly.

At present, well sites of most domestic oil and gas fields only have various dangerous notice boards, isolation guardrails, escape route maps and the like, and no personnel positioning, identifying and tracing systems exist. For example, some wellsites have personnel access management panels at the entrances that require personnel to access the wellsite to adjust the status of the access evidence as required (e.g., to indicate that personnel have entered or exited the wellsite) in time to confirm that personnel are still active at the wellsite in the event of an emergency. However, this method also has uncertainty due to human factors.

At least one embodiment of the present disclosure provides a well site personnel safety management method, including: acquiring position information of well site personnel; acquiring layout information of a well site, wherein the layout information comprises position information of a safe region, a dangerous region and a buffer region between the safe region and the dangerous region in the well site; an alarm signal is issued in response to wellsite personnel being located in the buffer zone or the hazardous zone to alert the wellsite personnel to the hazardous zone.

At least one embodiment of the present disclosure also provides a system and a storage medium corresponding to the above well site personnel safety management method.

The well site personnel safety management method provided by the embodiment of the disclosure can perform early warning when well site personnel are close to a dangerous area so as to avoid well site accidents caused by human factors, and meanwhile, the safety management targets of ' who you are, where you are, what how you are and what you are ' of the well site personnel ' are achieved.

Embodiments of the present disclosure and some examples thereof are described in detail below with reference to the accompanying drawings.

At least one embodiment of the present disclosure provides a wellsite personnel safety management system. Fig. 1 is a schematic structural diagram of a wellsite personnel safety management system according to at least one embodiment of the present disclosure; FIG. 2 is a wellsite area distribution diagram according to at least one embodiment of the present disclosure. A wellsite personnel safety management system provided in accordance with at least one embodiment of the present disclosure is described in detail below with reference to fig. 1 and 2.

For example, as shown in fig. 1, in some examples, the wellsite personnel safety management system 100 includes: positioning tag 101, positioning base station 102, server 103, data management platform 104 and terminal device 105.

For example, positioning tags 101 are worn by wellsite personnel and are configured to transmit location information of the wellsite personnel to positioning base station 102. For example, each wellsite person wears one positioning tag 101, and each positioning tag 101 has a unique identifier, so that the wellsite persons and the positioning tags 101 are in one-to-one correspondence, and therefore the position information of each wellsite person in the wellsite can be obtained according to the positioning tags. For example, the positioning tag 101 may be worn by a wellsite personnel by a workcard type (i.e., the positioning tag is embedded in the workcard), a safety helmet type (i.e., the positioning tag is embedded in the safety helmet), a wristband type (i.e., the positioning tag is embedded in the wristband), or other types, which are not limited in this respect by the embodiments of the present disclosure. For example, the positioning tag 101 may include a rechargeable battery to provide power to the positioning tag 101, and may further include an alarm unit to provide an audible and visual alarm, an SOS key alarm function, and the like, for example, the positioning tag 101 may also have a key intercom function, and the specific configuration may be set according to actual needs and specific situations, which is not limited by the embodiments of the present disclosure.

For example, the positioning tag 101 may be implemented as a positioning chip or a positioning circuit module, which may be stuck on the aforementioned work card, safety helmet, wrist strap, etc., and the embodiment of the present disclosure is not limited thereto. The specific structure can refer to the design in the field and is not described in detail herein.

For example, the positioning base station 102 is configured to transmit the received location information of the wellsite personnel to the server 103 and transmit instructions sent by the server 103 to the positioning tag 101 to enable data communication between the positioning tag 101 and the server 103.

For example, as shown in FIG. 2, positioning base station 102 is mounted to the edge of wellsite 2 or the edge of work area 4 within wellsite 2 such that the positioning tags worn by wellsite personnel 3 each fall within the coverage area of positioning base station 102, thereby enabling data communication of the positionable base stations. For example, the positioning tags 101 worn by the wellsite personnel 3 establish communication and data interactive transmission with the positioning base stations 102 in a wireless signal manner.

For example, as shown in FIG. 2, locating base station 1 requires determining the number of field installations based on the actual area and terrain of wellsite 2, which embodiments of the present disclosure are not limited in this regard.

For example, in some examples, the positioning base station 102 may implement the following functions through communication and data interaction with the positioning tag 101: determining the position information of the positioning tag 101 and sending the position information to the server 103; alarm and voice intercom signals between the positioning tag 101 and the server 103 are communicated to enable data communication between the positioning tag 101 and the server 103.

For example, server 103 is configured to obtain location information for wellsite personnel 3 and placement information for wellsite 2. For example, the layout information includes position information of a safe area within the wellsite 2, a hazardous area 5, and a buffer area 6 located between the safe area and the hazardous area 5.

For example, the operational area 4 within the wellsite 2 includes a safe area. For example, in some examples, the work area 4 serves as a safety area.

For example, the dangerous area 5 is located in the working area 4, and refers to a high-voltage area with pressure or an area with certain dangerous factors such as high-voltage electric equipment, etc., which may be determined according to actual situations, and the embodiment of the present disclosure is not limited thereto.

For example, the buffer zone 6 is located between the safe zone and the dangerous zone 5 for providing early warning when the wellsite personnel 3 approach the dangerous zone 5, thereby further preventing danger. For example, the buffer area may be enclosed at the periphery of the dangerous area 5, for example, an area where the dangerous area 5 is respectively extended outward by a certain distance in any direction is set as the buffer area, for example, an area enclosed by how many meters outside the dangerous area 5, which may be determined according to practical situations, and the embodiment of the present disclosure is not limited thereto.

For example, in some examples, the well site personnel safety management system software 1031 is run on the server 103 deployed in the well site command center and equipped with voice calling and sound playing equipment, and is responsible for establishing communication and data interactive transmission with the plurality of positioning base stations 102, so as to realize functions of configuration and management of the positioning tags associated with the well site personnel and information thereof, well site personnel position calculation, well site personnel safety management, data storage and the like.

For example, in some examples, the server 103 sends an alarm instruction to the location tag 101 to instruct an alarm unit of the location tag to issue an alarm signal in response to the wellsite personnel 3 being located in the buffer zone 6 or the hazardous zone 5, thereby alerting the wellsite personnel 3 away from the hazardous zone 5.

For example, the server 103 receives the position information of the wellsite personnel 3 transmitted from the positioning tag 101 in the wellsite 2 through the positioning base station 102, and when the server 103 judges that the wellsite personnel 3 are located in the buffer area 6 or the dangerous area 5, the server 102 transmits an alarm instruction to the positioning tag 101 to instruct an alarm unit of the positioning tag 101 to send an alarm signal, for example, send out a light alarm, a sound and light alarm, and the like, so as to warn the wellsite personnel 3 to be far away from the dangerous area 5, so that the real-time position information monitoring of personnel in each area in the wellsite can be realized according to the positioning tag position information transmitted by the positioning base station and information management data between the positioning tag and the wellsite personnel. For example, the real-time dynamic distribution of personnel in a well site is displayed, so that the site condition is vivid and clear at a glance; through supervision on the behavior of the staff, a good operation habit is formed, illegal operations are reduced, and the safety management quality is improved; and when the staff encounters danger, the rescue personnel can quickly find the positions of the staff according to positioning, so that the rescue efficiency is improved.

The server 13 may be a single server or a group of servers, each connected via a wired or wireless network. A group of servers may be centralized, such as a data center, or distributed. The server 13 may be local or remote.

For example, the data management platform 104 is configured to store layout information for the wellsite 2 and to retrieve and store activity trajectory data for wellsite personnel from the server 103.

For example, in some examples, the data management platform 104 is further configured to store profile information of the wellsite personnel, for example, the positioning tags 101 correspond to the profile information of the wellsite personnel one by one, so that the location information obtained by the positioning tags corresponding to the wellsite personnel can be obtained by filling identification information of the wellsite personnel, such as identity information, on the terminal device 105. For example, the profile information may include names, affiliated companies, position names, authority information, and the like of the well site personnel, for example, the association configuration and management (including binding/unbinding of the positioning tag to the well site personnel, health status monitoring of the positioning tag, and the like) of the positioning tag 101 and the well site personnel profile information may implement a corresponding relationship in the server 103, and transmit the corresponding relationship to the data management platform 104 for storage.

The data management platform 104 may be implemented as a database, which may broadly refer to a device with storage capabilities, for example. The data management platform 104 is mainly used for storing various data utilized, generated, and outputted from the terminal device 105 and the server 103 in operation. For example, the data management platform 104 stores the layout information of the well site 2 and acquires and stores the activity track data of the well site personnel from the server 103, when the server 103 responds to the inquiry operation of the terminal device 105 (for example, the operation of inquiring the activity track of a certain well site personnel in a certain time period) to read the activity track of the well site personnel in the time period from the data management platform 104 and transmit the activity track of the well site personnel in the time period to the terminal device 105 through the network 106, the terminal device 105 displays the activity track of the well site personnel in the time period, so that the real-time dynamic distribution of the personnel in the well site can be displayed, and the live situation is vivid; through supervision on the behavior of the staff, a good operation habit is formed, illegal operations are reduced, and the safety management quality is improved; and when the staff encounters danger, the rescue personnel can quickly find the positions of the staff according to positioning, so that the rescue efficiency is improved.

The data management platform 104 may be local or remote. The data management platform 104 may include various memories, such as a Random Access Memory (RAM), a Read Only Memory (ROM), and the like. The above mentioned storage devices are only examples and the storage devices that the system can use are not limited to these.

The data management platform 104 may be interconnected or in communication with the server 103 or a portion thereof via the network 106, or directly interconnected or in communication with the server 103, or a combination thereof.

In some embodiments, the data management platform 104 may be a standalone device. In other embodiments, the data management platform 104 may also be integrated in at least one of the terminal device 105 and the server 103. For example, the data management platform 104 may be provided on the terminal device 105 or may be provided on the server 103. For another example, the data management platform 104 may be distributed, and a part thereof may be provided in the terminal device 105 and another part thereof may be provided in the server 103.

For example, the network 106 may be a single network, or a combination of at least two different networks. For example, the network 106 may include, but is not limited to, one or a combination of local area networks, wide area networks, public networks, private networks, and the like. For example, in some examples, several wireless positioning base stations are communicatively coupled to the server 103 via a wired network, an ethernet network, or a wireless network (e.g., WiFi).

For example, terminal equipment 105 is configured to enable monitoring and querying of the activity trajectory of wellsite personnel 3 based on wellsite personnel activity data stored by data management platform 104.

For example, the terminal device 105 may be a computer, a mobile phone, or the like. It is to be appreciated that the terminal device 105 may be any other type of electronic device capable of performing data processing, which may include, but is not limited to, a desktop computer, a laptop computer, a tablet computer, a smartphone, a smart home device, a wearable device, a vehicle-mounted electronic device, a monitoring device, and the like. The terminal device may also be any equipment provided with an electronic device, such as a vehicle, a robot, etc.

In order to implement the necessary functions of the wellsite personnel safety management system 100, those skilled in the art may provide and arrange other components not shown according to specific needs, and the embodiment of the disclosure is not limited thereto.

The well site personnel safety management system provided by the embodiment of the disclosure can perform early warning in advance when well site personnel are close to a dangerous area, so that well site accidents caused by human reasons are avoided, and meanwhile, the safety management target of 'who you are (who), where you are (where), what you are (how), what do (what)' of the well site personnel is realized. In addition, when an emergency occurs, the system can rapidly alarm and display the position of emergency well site personnel so as to take the most effective measures to ensure the personal safety of the personnel in the well site to the maximum extent.

At least one embodiment of the present disclosure further provides a well site personnel safety management method, for example, the well site personnel safety management method is executed and implemented by the server in the well site personnel safety management system, and may also be executed and implemented by other processors, which is not limited in this respect.

Fig. 3 is a flowchart of a wellsite personnel safety management method according to at least one embodiment of the present disclosure. A method for managing wellsite personnel safety provided by at least one embodiment of the present disclosure is described in detail below with reference to fig. 3.

For example, in some examples, as shown in fig. 3, the wellsite personnel safety management method includes steps S110 to S130.

Step S110: acquiring position information of well site personnel;

step S120: acquiring layout information of a well site, wherein the layout information comprises position information of a safe region, a dangerous region and a buffer region between the safe region and the dangerous region in the well site;

step S130: an alarm signal is issued in response to wellsite personnel being located in the buffer zone or the hazardous zone to alert the wellsite personnel to the hazardous zone.

In step S110, for example, in some examples, server 103 receives location information of wellsite personnel 3 transmitted from positioning tag 101 in wellsite 2 through positioning base station 102; for example, in other examples, the location information of the wellsite personnel at any time period is uploaded to the data management platform 104 by the server 103 for storage, so that when the user invokes the activity track of a wellsite personnel at a time period by moving the APP through the wellsite personnel safety management system on the terminal device, the server 103 can invoke the location information of the wellsite personnel at the time period, namely the activity track, from the data management platform 104.

In step S120, for example, in some examples, the wellsite personnel safety management system supports wellsite scenario configuration and management, supporting import of wellsite layout maps. For example, the wellsite layout may be uploaded by the server to the data management platform 104 for storage, such that the specific location of the wellsite personnel may be determined based on the wellsite personnel location information and the wellsite layout.

For example, in some examples, the layout information of the wellsite may include a functional zone, a safety management level zone, a number of positioning base stations, an installation location, and the like of the wellsite, and may further include a terrain size of the wellsite, and the like, which is not limited by the embodiments of the present disclosure.

For example, in this example, the method further comprises: and determining position information of a safe area, a dangerous area and a buffer area of the well site according to the functional partition and the safety management grade partition of the well site.

For example, the operational area 4 within the wellsite 2 includes a safe area. For example, in some examples, the work area 4 serves as a safety area.

For example, the dangerous area 5 is located in the working area 4, and refers to a high-voltage area with pressure or an area with certain dangerous factors such as high-voltage electric equipment, etc., which may be determined according to actual situations, and the embodiment of the present disclosure is not limited thereto.

For example, the buffer zone 6 is located between the safe zone and the dangerous zone 5 for providing early warning when the wellsite personnel 3 approach the dangerous zone 5, thereby further preventing danger. For example, the buffer area may be enclosed at the periphery of the dangerous area 5, for example, an area where the dangerous area 5 is respectively extended outward by a certain distance in any direction is set as the buffer area, for example, an area enclosed by how many meters outside the dangerous area 5, which may be determined according to practical situations, and the embodiment of the present disclosure is not limited thereto.

In step S130, for example, when the server 103 determines that the wellsite personnel 3 are located in the buffer area 6 or the dangerous area 5, the positioning base station 102 sends an alarm instruction to the positioning tag 101 to instruct the alarm unit of the positioning tag 101 to send an alarm signal, for example, send out an optical warning, an acoustic warning, an acousto-optic warning, or the like, so as to alert the wellsite personnel 3 away from the dangerous area 5, so that real-time location information monitoring of personnel in each area in the wellsite can be realized according to the positioning tag location information transmitted by the positioning base station and the information management data between the positioning tag and the wellsite personnel. For example, the real-time dynamic distribution of personnel in a well site is displayed, so that the site condition is vivid and clear at a glance; through supervision on the behavior of the staff, a good operation habit is formed, illegal operations are reduced, and the safety management quality is improved; and when the staff encounters danger, the rescue personnel can quickly find the positions of the staff according to positioning, so that the rescue efficiency is improved.

FIG. 4 is a flow chart of another wellsite personnel safety management method in accordance with at least one embodiment of the present disclosure. For example, as shown in fig. 4, based on the example shown in fig. 3, the wellsite personnel safety management method further includes steps S210 to S230.

Step S210: acquiring the advancing speed of well site personnel towards a dangerous area;

step S220: judging whether the forward speed is greater than a preset threshold value or not;

step S230: in response to the forward speed being greater than a preset threshold, an alert signal is issued to wellsite personnel.

In step S210, for example, a speed sensor, a gyroscope, a direction sensor, and the like are provided in the positioning tag 101, and the advancing speed of the wellsite personnel toward the dangerous area is acquired by the speed sensor, the gyroscope, and the direction sensor, and is transmitted to the server 103 through the positioning base station 102.

In step S220, for example, the preset threshold may be determined according to actual situations, and embodiments of the present disclosure are not limited thereto.

In step S230, for example, when the server 103 determines that the wellsite personnel 3 are located in the buffer area 6 and the advancing speed is greater than the preset threshold, an alarm instruction is sent to the positioning tag 101 through the positioning base station 102 to instruct an alarm unit of the positioning tag 101 to send an alarm signal, for example, a light alarm, a sound-light alarm, or the like, so as to alert the wellsite personnel 3 away from the dangerous area 5.

For example, in embodiments of the present disclosure, it may be predetermined whether the wellsite personnel anticipate a dangerous area by determining the rate of advancement of the wellsite personnel toward the dangerous area, which may indicate a controlled degree of danger to the wellsite personnel when the rate of advancement is greater than a predetermined threshold, thereby providing a warning to alert the wellsite personnel that a dangerous situation is about to occur, thereby avoiding the transmission of the danger.

FIG. 5 is a flow chart of another wellsite personnel safety management method in accordance with at least one embodiment of the present disclosure. For example, as shown in fig. 5, based on the example shown in fig. 4, the wellsite personnel safety management method further includes steps S310 to S330.

S310: acquiring the file information of well site personnel, wherein the file information of the well site personnel comprises authority information of the well site personnel;

s320: judging whether an alarm signal is triggered when the well site personnel are located in a buffer area or a dangerous area based on the authority information of the well site personnel;

s330: an alarm signal is triggered when wellsite personnel are located in the buffer zone or the hazardous zone in response to the wellsite personnel not having access to the hazardous zone.

In step S310, for example, in some examples, the data management platform 104 stores profile information of the wellsite personnel, for example, the positioning tags 101 correspond to the profile information of the wellsite personnel one by one, so that the location information obtained by the positioning tags corresponding to the wellsite personnel can be obtained by filling identification information, such as identity information, of the wellsite personnel on the terminal device 105. For example, the profile information may include names, affiliated companies, position names, authority information, and the like of the well site personnel, for example, the association configuration and management (including binding/unbinding of the positioning tag to the well site personnel, health status monitoring of the positioning tag, and the like) of the positioning tag 101 and the well site personnel profile information may implement a corresponding relationship in the server 103, and transmit the corresponding relationship to the data management platform 104 for storage.

For example, the authorization information indicates the authorization of the activity area of the wellsite personnel, and whether there is authorization or other authorization to enter the dangerous area, and the embodiments of the present disclosure are not limited thereto.

In step S320, it may be determined whether an alarm signal is triggered when the wellsite personnel are located in a buffer zone or a hazardous zone, for example, based on the wellsite personnel authorization information. For example, when wellsite personnel have access to the hazardous area, no warning, i.e., no alarm signal is triggered, is provided when the wellsite personnel are located in the buffer area or the hazardous area, or are traveling toward the hazardous area at a speed greater than a preset speed.

In step S330, when the personnel in the wellsite do not have the right to enter the dangerous area, the alarm signal is triggered when the personnel in the wellsite are in the buffering area or the dangerous area, so that the alarm information can be accurately sent, unnecessary early warning is avoided, and personnel panic is caused, thereby improving the operating efficiency of the personnel in the wellsite.

For example, in other examples, as shown in fig. 2, an electronic fence may be installed in a dangerous area 5 in a wellsite, and when a wellsite person 3 without access authority enters the area, the system triggers an alarm prompt message and sends an alarm command to a positioning tag carried by the wellsite person 3, and the positioning tag sends an audible and visual alarm signal after receiving the alarm command. The system management personnel can also send voice calls to the positioning tags carried by the well site personnel 3 through the voice talkback function in the system, and issue evacuation commands to the well site personnel 3, so that danger caused by artificial reasons is avoided.

For example, in other examples, the wellsite personnel safety management method further comprises, in response to wellsite personnel being located in a hazardous area and not authorized to trigger the alarm signal: and planning a route for evacuating the dangerous area for the well site personnel according to the position information of the well site personnel and the layout information of the well site. For example, in this example, the evacuation direction and the evacuation route of the personnel in the well site may be informed in a voice announcement manner, and the evacuation route may also be displayed on a display screen of the positioning tag, which may be set according to the actual situation, and the embodiment of the present disclosure is not limited thereto.

It should be noted that the method for evacuating the route of the dangerous area may adopt the technical method in the field, and the detailed description is omitted.

For example, in some examples, the wellsite personnel safety management method further comprises: acquiring the time length of well site personnel in the same position and the number of the well site personnel in the same position; monitoring the well site personnel overtime and immovable based on the time length of the well site personnel in the same position; the number of the well site personnel located at the same position is used for carrying out crowd monitoring on the well site personnel, so that real-time monitoring on the well site personnel is realized.

For example, by establishing an algorithm model, the intelligent management of the personnel safety of the well site is realized by monitoring the behaviors of all personnel in the well site area in real time, including overtime monitoring, crowd monitoring, motionless monitoring and the like, the management quality is improved, and the personnel safety of the personnel is guaranteed.

For example, in other examples, the wellsite personnel safety management method further comprises: and receiving alarm information sent by well site personnel, and judging the dangerous case according to the alarm information so as to send a rescue prompt signal to implement corresponding rescue operation.

In the example, when dangerous conditions occur in the operation process of well site personnel in the well site, the personnel can send alarm information to the well site personnel safety management system in real time by repeatedly pressing the SOS key on the positioning label carried at any time; also can initiate with well site personnel safety control system managers through pressing the button of talkbacking and report to the police to when well site staff runs into danger, can call for help and early warning at the very first time, the rescue personnel can find staff's position rapidly according to the location, improves rescue efficiency, guarantees well site safety.

For example, in some examples, the wellsite personnel safety management method further comprises: the method comprises the steps of acquiring activity track data of well site personnel to count and query the behaviors of the well site personnel, so that functions of real-time activity track viewing of the well site personnel, activity track playback and exit/entry region in any period of time, behavior counting and querying violating safety management and the like can be realized.

For example, in the embodiment of the present disclosure, the data management cloud platform 104 reads and stores the scene configuration of the well site, the real-time location information of all the personnel in the well site, and the well site personnel archive information from the server 103, and can implement real-time monitoring of the real-time location of the personnel in the well site and the alarm triggering condition on any client computer at any time and any place, and also can view the real-time activity track of any well site personnel, play back the activity track at any time, enter/exit the area, perform statistics and query violating safety management, and the like.
