摘　　要：针对水平井尾管导向钻井技术存在的钻机旋转系统负载大、地面扭矩传动效率低、使用与维护成本高等问题,提出了水平井双管柱尾管差速旋转钻进新方法,揭示了相应的技术原理,设计了双管柱差速旋转传动、复合旋转导向及悬挂器等井下专用工具,优化了相关工艺流程;提出了导向钻具组合工具面控制方法,建立了水平井双管柱尾管差速旋转钻进延伸极限计算模型。结果表明:水平井双管柱尾管差速旋转钻进技术配备常规随钻测量仪器和螺杆钻具,通过调节钻柱转速可以控制导向钻具组合的工具面,实现了水平井双管柱尾管差速旋转导向钻进;基于鄂尔多斯盆地东缘深部煤层气水平井工程案例计算水平井双管柱钻进延伸极限,与常规尾管钻井方式相比,采用双管柱尾管差速旋转钻进方式显著增大了水平井延伸极限,为水平井尾管完井与钻井一体化设计控制提供了参考。Aiming at the problems of large load of rotation drive system of rig,low efficiency of torque transmission and high cost for operation and maintenance in the horizontal well liner steering drilling technology,a new method of liner differential rotation drilling with double tubular strings in the horizontal well is proposed.The technical principle of this method is revealed,supporting tools such as the differential rotation transducer,compound rotary steering system and the hanger are designed,and technological process is optimized.A tool face control technique of steering drilling assembly is proposed and the calculation model of extension limit of liner differential rotary drilling with double tubular strings in horizontal well is established.These results show that the liner differential rotary drilling with double tubular strings is equipped with measurement while drilling(MWD) and positive displacement motor(PDM),and directional drilling of horizontal well is realized by adjusting rotary speed of drill pipe to control the tool face of PDM.Based on the engineering case of deep coalbed methane horizontal well in the eastern margin of Ordos Basin,the extension limit of horizontal drilling with double tubular strings is calculated.Compared with the conventional liner drilling method,the liner differential rotary drilling with double tubular strings increases the extension limit value of horizontal well significantly.The research findings provide useful reference for the integrated design and control of liner completion and drilling of horizontal wells.
