Background

In oil field development, tens of thousands of oil-water wells are operated every day. The oil pipe is a channel for connecting a wellhead and an oil layer and is used as an important component of oil-water well production, and the management level of the oil pipe is directly related to the length of the repair-free period of the oil-water well and the height of the operation cost. The number of oil pipes in each oil production plant is huge. According to the introduction of a certain oil production factory, the cost of an oil pipe rod accounts for 21% of the material cost of the oil production factory and 55% of the operation main material cost. Disproportionately, under the restriction of factors such as technology and equipment, the management and use of the oil pipe are relatively extensive, and the fine management is urgently needed. The main problems are represented by: firstly, the old and new are mixed, and the service life difference of the oil pipe of the same well is large. Because the oil pipe is replaced on the operation site for a long time, the oil pipes of the same well are used in a new and old mode, and the service life, the fatigue degree and the material are different. Under the same well environment and stress, the oil pipes with long service life, high fatigue degree and poor material are prone to have problems, a 'short service life plate' is formed, the pump inspection operation is frequent, and the effect of the replaced part of new oil pipes cannot be effectively exerted. Secondly, the field management of oil pipes is disordered, the quantity of pipes in each mine area is not clear, the storage site of the oil pipes is not standard, the oil pipes are placed in a disordered manner, and when the oil pipes in different ages are mixed together for recovery and repair, because the pipes with long and short ages cannot be selected and mixed together for on-line selection and repair, the quantity and the quality of the pipes cannot be clearly distinguished due to the mixing of the repair pipes, part of defective oil pipes are lowered into the well again, breaking and piercing are formed, the pump inspection operation is frequent, and the improvement of the underground operation quality and the extension of the repair-free period are severely restricted.

In order to solve the restriction of oil pipe problems on the operation cost and quality, under the condition of full preliminary investigation, based on the establishment requirement of a digital oil field on a digital shaft, an identification code needs to be given to each oil pipe, a 'family mouth' file is established for each oil pipe, and information such as oil pipe warehousing time, service time, place, maintenance time, maintenance reasons, maintenance results, scrapping time and the like is traced, so that the information such as the production life, the service life, the use times, the use effect and the like of the oil pipe of the oil-water well is accurate and reliable. According to the requirement, the oil pipes with different materials, qualities and ages can be selected in a targeted manner, and the method has great guiding significance for deepening the management of the whole life cycle of the oil pipe.

The two-dimensional code technology and the RFID chip embedding technology are sequentially researched through field test, but under a complex underground environment, the identification of the two technologies is easy to lose effectiveness. Through repeated research and exploration, the oil pipe identification combining the clip positioning and the bar codes is adopted, the clip positioning is to carve a clip shape for identification positioning, the bar codes are that each oil pipe adopts a 26-bit binary identification code, the nicks represent '1' and no nicks represent '0', the nicks have a depth of 0.3 mm, and respectively represent information of manufacturers, specification models, materials, well numbers, production time and the like. The oil pipe identification can be used in a high-temperature, vibrating, wearing and corroding underground environment, and can also read data. Therefore, it is necessary to develop a code-carving device, which can precisely carve the code on the oil pipe body for the oil pipe identifier combining the clip positioning and the bar code.
