摘　　要：建立了XXJ30 0 / 5 0 0液压蓄能修井机在各力档下下放管柱时的动力学方程式。通过求解动力学方程式 ,分析了各力档下的管柱下放速度随管柱位移变化的动态特性 ,得出了管柱重量以及节流阀通流面积对管柱下放速度的影响规律。The dynamics equation of XXJ300/500 hydraulic energy-storing workover rig during lifting pipestring under each force grade was established. The dynamic performances of the lowering velocity of pipestring changing with movement of pipestring were analyzed by the dynamics equation. The affecting law of the pipestring’s weight and the throttle valve path area to the lowering velocity of pipestring was obtained.
