Background
In the production of the petroleum industry, a large number of downhole tools are needed to complete the drilling construction operation process, so that the good working performance of the downhole tools is the fundamental guarantee for the effective implementation of the production operation. However, under severe conditions such as high temperature and vibration in the well, the working state of the downhole tool is constantly changed, and once a fault occurs, it is difficult to find out the fault point, which not only affects the normal operation of the construction operation, but also brings difficulty to the later maintenance of the tool. Therefore, it is necessary to detect the performance parameters of the tool before the tool enters the well to ensure that the tool meets the design and construction requirements, track and record the working state of the tool in real time after the tool enters the well, and combine the detection data before and after the tool enters the well after the tool exits the well to serve as the basis for judging the fault reason and finding and controlling the drilling accidents in time, thereby achieving the purpose of safe, efficient and low-cost drilling.
The ground detection of the comprehensive parameters of the current downhole tool mainly verifies the integral working performance of the tool by simulating the downhole working condition, for example, a comprehensive parameter detection and test system of a full-size downhole oil extraction tool developed by Daqing oil fields can be used for detecting various oil extraction tools including combination tools, a complete machine performance test device of the downhole tool developed by Shengli oil field drilling and production institute can measure parameters such as pressure, tension and compression load, torsion load, displacement, rotation angle and the like in real time, and a downhole tool test system developed by Dagang oil field drilling and production institute can carry out high-pressure liquid circulation test while testing the mechanical performance such as tension, compression, torsion and the like of the drilling and production tool; the research on the working state of the tool after entering the well mainly focuses on monitoring the dynamic parameters of the downhole tool, for example, the DrillDOC tool developed by Halliburton corporation in America can measure the parameters of bit pressure, torque, bending moment and the like in real time and optimize the parameters to play the maximum working performance of a downhole drilling tool combination, an instrumented bit developed by Security DBS corporation can detect the bit pressure, the torque, the acceleration, the center track of the bit, the eccentricity of a borehole and the like, an engineering parameter measuring instrument jointly developed by China middle and high-sea oil research center and southwest oil university can simultaneously measure the bit pressure and the torque at the position close to the bit, and a near bit engineering parameter measurement based on a resistance-type gunn strain gauge such as a gorgeon peak of China oil university can realize the measurement of the bit pressure, the torque, the annular pressure, the pressure inside and outside pressure of the drill collar.
In conclusion, the ground detection and downhole monitoring technology of downhole tool performance parameters is mature day by day, and the downhole tool performance parameter testing device has the advantages of more measurement parameters, high precision, good stability and good safety, but can only test the tool before and after entering the well.
