摘　　要：粘滑振动一直是影响深井、超深井原油开采效率及成本的关键因素之一,旋冲发生器可有效地辅助钻井工具解决粘滑振动问题。针对国内旋冲发生器运行稳定性能尚不完善,提出了一种水平旋冲运动发生器的原理,建立了动力学模型并对此结构的内部流场进行了仿真,分析了内部流场及压力特征,确定了结构特征。实验与仿真结果表明,依据理论确定结构特征可提供稳定的工作性能,证明了理论的可靠性和准确性。Stick slip vibration has always been one of the key factors affecting the efficiency and cost of deep well and ultra deep well crude oil exploitation,the rotary punching generator can effectively assist the drilling tool to solve the stick slip vibration problem.In view of the imperfection of the operation stability of the domestic rotary impulse generator,this paper presents a structural design scheme of the horizontal torsion impactor.The transient dynamic model of hydraulic hammer of horizontal torsion impactor is established and the internal flow field of the structure is simulated.The internal flow field and pressure characteristics are analyzed and the structural characteristics are determined.The experimental and simulation results are compared and analyzed.The results show that the theoretical determination of structural characteristics can provide stable performance,which proves the reliability and accuracy of the theory.
