摘　　要：粒子冲击钻井技术是一种用于解决石油天然气深井硬地层钻井钻速慢和成本高的问题。该技术利用钻井液的水力能量携带的圆形钢粒以极高的速度冲击破碎岩石,钻井液所携带的钢粒会对钻具产生冲蚀磨损,尤其是在管径变化和管道弯曲处,钢粒对管壁的冲蚀磨损会导致钻具安全性降低,保障粒子冲击钻井安全作业是粒子冲击钻井技术研究的重要内容。为此,分析了影响钻具冲蚀磨损的因素,结合粒子钻井现场实际,研制出一种用于地面模拟粒子冲击钻井中钻具冲蚀磨损的实验装置,根据粒子冲击钻井实验提出,对较易磨损的弯接头、冲管、滤芯三通、鹅颈管等部件要进行镀镍防磨、耐磨处理。以确保粒子冲击钻井的安全。Particle impact drilling technology is used to solve the problems of slow drilling rate and high cost in hard formation drilling. The technology uses hydraulic energy of drilling fluid to make round steel particles impact crushing rocks with high speed,but the steel particles will produce erosion and wear to drilling tool,especially in pipe diameter changes and pipe bends. The erosion and wear of pipe wall will make drilling tool safety reduce. So,the factors affecting the drilling tool erosion were analyzed. Combined with the field particle drilling technology,a experimental installation used for ground simulating drilling tool erosion in particle impact drilling was developed. Based on the results in experiment,some wear resistant measures of wearing parts were proposed to ensure the safety of particle impact drilling.
