摘　　要：液动周向扭矩冲击发生器是抑制钻井过程中"卡-滑"现象的有效措施。介绍了液动周向扭矩冲击发生器的结构和工作原理,建立了该扭冲器的流道分布模型,计算了其工作过程中各流道的流量,确定了典型零件冲击过程中的运动参数和瞬时冲击载荷,得出了液动周向扭矩冲击发生器的冲击扭矩及旋转频率。试验情况表明,计算结果与实际工况比较接近,这为扭冲器的设计和使用提供了依据。The circumferential torque hydraulic shock generator may effectively inhibit 'stuck and slip'during the process of drilling operations. This paper presents the structure and principles of the circumferential torque hydraulic shock generator,and provides the flow distribution model of the device. The flow rates in various channels in the working process of the device are calculated. In addition,the motion parameters and the instantaneous impact loads of typical parts in the process of impact are clarified,and torque and rotation frequency of the shock generator are determined. The test shows that the calculation results are consistent with the actual working conditions. Relevant results provide a basis for application of the device.
