Tubing and sucker rod identification and tracking system

Abstract

An oil pipe and sucker rod identity recognition tracking system relates to the technical field of oil field downhole tools and comprises a detection probe, a chip, a chip reading device and a coupling, wherein the detection probe is mounted on a mounting cylinder independent of a wellhead; the chip is mounted on the upper end face of the coupling; the chip is a radio frequency electronic tag; thechip reading device is a radio frequency reader-writer; the structure of the radio frequency reader-writer comprises a radio frequency reader-writer host and a radio frequency antenna; the radio frequency antenna is connected with the radio frequency reader-writer host through a wire; the radio frequency antenna is arranged on the inner side of the mounting cylinder; and the radio frequency antenna is connected with the radio frequency reader-writer host through a wire. The chip is arranged on the upper end face of the oil pipe coupling or the sucker rod coupling (collectively called coupling)instead of the oil pipe or the sucker rod, the installation mode cannot affect use of the coupling, and meanwhile weakening of the strength of the oil pipe or the sucker rod due to installation of the chip is avoided.

Description

technical field [0001] The invention belongs to the technical field of oilfield downhole tools, in particular to an identification and tracking system for oil pipes and sucker rods. Background technique [0002] In the pumping unit oil production system, the oil pipe and sucker rod in the oil well will leak or break due to cracks, holes, corrosion, and wear. Once this happens, it will cause large economic losses to the oil field. Therefore, Effective management of tubing and sucker rod damage is essential. In the prior art, the inspection method of pulling all the oil pipes and sucker rods back to the inspection station for flaw detection is mostly used to realize the inspection. This method has two defects: on the one hand, it consumes a lot of manpower and material resources; on the other hand, it is difficult to inspect each It is impossible to make full use of each tubing or sucker rod, and it is impossible to accurately judge the problems existing in the downhole accor...

Problems solved by technology

In the prior art, the inspection method of pulling all the oil pipes and sucker rods back to the inspection station for flaw detection is mostly used to realize the inspection. This method has two defects: on the one hand, it consumes a lot of manpower and material resources; on the other hand, it is difficult to inspect each It is impossible to make full use of each tubing and sucker rod, and it is impossible to accurately judge the problems existing in the downhole according to the damage status

However, in actual use, it is found that there are the following problems in the implementation of this method: to realize the reading of the chip, a communication connection must be established with the chip, and how to set the communication mode, how to ensure the effectiveness of chip identification, and how to reduce the hardware of the communication system Cost, how to set up the chip identification device in the narrow annular space between the casing and the oil pipe, etc., this series of problems must be solved through a lot of creative labor
