Optimal Design of Horizontal Well Traction Robot Traction Force Regulating Mechanism

Production section testing technique is an important kit technique of horizontal well development. And traction robot technology is the core technology. Downhole driving unit is a very important part of traction robot, it can be used to implement a variety of sports instruction of control system, so that the traction robot can walk in the pipeline, to sent the test equipment to the destination, and the crawling round can be recovered automatically when the system is powered down. This paper give out the overall design of downhole driving unit, and then the traction regulating mechanism has been optimized: first, created a mechanical model of traction control mechanism, and then optimize the important structure parameters of the adjustment mechanism.
