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.
Abstract
In the exploration and development of oil and gas resources in China,conventional drilling tech-nologies 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 con-crete 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.
