摘要 针对水平井钻井、测井过程中管串下入困难的问题,研制了伸缩式井下机器人,而控制系统是影响伸缩式井下机器人可靠性、稳定性的关键技术。基于伸缩式井下机器人的工作原理,提出了一种新的伸缩式井下机器人电液控制系统,并综合考虑电、液系统和执行机构,建立了基于电液耦合控制的数值仿真模型。通过分析机器人系统排量、牵引力及井眼直径对其运动性能的影响,揭示了机器人在不同工作参数条件下的运动规律,并设计了一套电液控制系统试验方案,研究了系统排量对机器人运动周期的影响规律。试验结果表明,不同系统排量下机器人运动周期的仿真曲线和试验曲线趋势基本一致。研究结果为液压伸缩式井下机器人的设计和现场应用提供了理论依据。 a telescopic downhole robot was developed,whose control system is the key point that affects its reliability and stability as well.According to the working mechanism of the robot,a novel electro-hydraulic control system was innovated.Further,a numerical simulation model based on electro-hydraulic coupling control was established by comprehensively considering the electric and hydraulic systems,and actuators as well.By analyzing the influence of system fluid rate,traction,and wellbore diameter on the robot kinematics,the movement of the robot under different working parameters was revealed.An experimental scheme of the electro-hydraulic control system was designed,and the influence of the system fluid rate on the motion cycle of the robot was studied.The experimental results show that the simulation curve of the motion cycle of the robot under different system fluid rate is basically consistent with the experimental curve.The research results can provide a theoretical basis for designing and studying hydraulic telescopic downhole robots.
