Abstract

The invention discloses a loading control method for a dynamic offset directional rotary steering drilling tool test bed. The method comprises the following steps: respectively establishing transfer functions of a hydraulic cylinder, a magnetic powder brake and a proportional overflow valve of an analog loading device according to mathematical models thereof; calculating the relation between inputand output by using a fuzzy self-adaptive PID controller through a fuzzy reasoning method, and carrying out the optimal adjustment of PID parameters; then, applying a Simulink module in Matlab software to compare the simulation result of the designed control method with the simulation result of a conventional PID control method; results show that the fuzzy adaptive PID control method has faster response time and better anti-interference capability; research results show that the control method is feasible for an analog loading system of the dynamic offset directional rotary steering drillingtool test bed, the response speed of the system is increased, and the stability of the system is better.

Description

technical field [0001] The invention belongs to the technical field of rotary steerable drilling, in particular to a method for controlling the loading of a test bench of a dynamic offset pointing type rotary steerable drilling tool. Background technique [0002] In oil drilling engineering, it is necessary to test the performance of the dynamic bias pointing rotary steerable drilling tool. Due to the complex structure and high cost of the dynamic bias pointing rotary steerable drilling tool, there is no independent research and development in my country that can be successfully commercialized. The applied dynamic bias pointing rotary steerable drilling tool cannot conduct in-depth and professional research on the performance of the dynamic bias pointing type steerable drilling tool, and there is still a lot of room for exploration in this experimental research. refer to figure 1 , figure 2 , Patent No. CN107219084A discloses a performance test bench for dynamic offset poi...
