摘　　要：针对传统石油钻井工具在深井、硬质地层中钻进效率低,钻井成本高,粘滑振动现象严重等缺点,设计了一种新型脉动扭转冲击钻井工具。该脉动扭转冲击钻井工具由冲击装置和换向装置组成,利用Pro/E建立了脉动扭转冲击装置的分析模型并利用XFLOW分析内部流场及压力分布,设置不同工作状态下的边界条件,得到该工具不同工作状态下的压力分布云图和出口平均压力曲线。仿真结果表明,冲击锤的周向运动由两侧的压差驱动;压降参数与美国的Torkbuster基本相同,性能具有相关性;出口平均压力变化小,可以稳定工作,为脉动扭转冲击装置内部结构设计及性能优化提供参考依据。Aiming at conventional drilling tools＇ defects, such as low drilling efficiency, high cost, serious phenomenon of stick-slip vibration in deep well and competent formation, a new type of pulsant torsional impactor was designed. The pulsant torsional impactor is composed of impacting device and reversing device. An analysis model of pulsant torsional impactor was established by Pro/E, the airflow and pressure distribution were analyzed using the XFLOW software. Setting up the boundary conditions under different working conditions, the pressure distribution and outlet average pressure curve of the tool under different working conditions are obtained. The simulations shows ： the impact hammer is driven by differential pressure, the value of difference is minus, this device has relationship with American Torkbuster in property and their pressure drop are similar, and the average pressure changes slightly in outlet. All these characters provide the model of internal structure design and performance optimization for further study.
