摘　　要：我国油气资源勘探开发中常规钻井技术在钻遇石英砂岩、燧石、高硅质砂岩、黄铁矿和火成岩等难钻地层时,面临“钻速慢、进尺短”的钻井瓶颈。为此,基于粒子高频冲击破岩原理,借鉴高层建筑混凝土配浆-注浆和常压混凝土储存方法,设计了双活塞换向机构、防粒子沉淀物料罐、动态回收储存装置、高效分离装置和2D/3D自动化监控系统,研制了1套自控型粒子冲击钻井系统,并在江沙X1井对其进行了现场试验。试验结果表明:该系统运行稳定可靠,粒子回收率达到98.7%,平均机械钻速15 m/h,与邻井同地层螺杆配PDC钻头钻进方式相比平均机械钻速提高1.52倍。所得结论可为深层及复杂坚硬地层钻井提速提供技术支撑。In the exploration and development of oil and gas resources in China,conventional drilling technologies are challenged by the bottlenecks such as low rate of penetration(ROP)and short footage when they are applied in hard-to-drill formations such as quartz sandstone,flint,high siliceous sandstone,pyrite and igneous rock.Based on the principle of particle high-frequency impact rock-breaking,and referring to the methods of concrete mixing-grouting and atmospheric pressure concrete storage in high-rise buildings,the double-piston reversing mechanism,particle deposit prevention bucket,dynamic recovery and storage device,efficient separation device and 2D/3D automatic monitoring system were designed,and a self-controlled particle impact drilling system was developed,which was tested in Well JS-X1.The test results show that the system operates stably and reliably,with a particle recovery rate of 98.7%and an average ROP of 15 m/h,1.52 times more than that of the PDM drill+PDC bit process in the same formation of adjacent wells.The research conclusions provide technical support for improving ROP in drilling deep and complex hard formations.
