国外钻井工具与仪器新进展及国内发展建议

New advances in drilling tools and instruments abroad and suggestions for domestic development

页岩气、致密油气、深井超深井油气和深水油气的勘探开发对钻井工具与仪器提出了更高要求。本文介绍了国外钻井工具与仪器的新进展,钻井工具包括高效破岩钻头(Aegis铠装合金钻头、Crush&Shear™混合式钻头、智能自适应钻头、StrataBlade*凹面金刚石元件钻头和HyperBlade*双曲面金刚石元件钻头)、辅助破岩工具(Navi-Drill DuraMax井下马达、NitroForce™高性能螺杆和耐温300℃螺杆钻具)和循环短节(iCWD智能循环短节、iDisc智能循环和丢手工具、MOCS G2循环短节和JetStream®RFID循环短节),而钻井仪器包括旋转导向工具(Lucida高端旋转导向系统、RST旋转导向系统、VectorEDGE旋转导向系统、HALO高性能旋转导向系统和NeoSteer@bit导向系统)和随钻测量仪器(TruLink*高分辨率动态MWD、IriSphere*随钻前视LWD、HEX200℃高温LWD和QuestTM随钻陀螺测斜仪)。在此基础上,对国内钻井工具与仪器的未来发展提出了建议。最后指出我国应尽快完成核心钻井工具与仪器的国产化,继续加大低成本替代技术的研究力度,以实现经济有效开发。

Exploration and development of shale gas,tight oil and gas,deep and ultra‑deep well oil and gas,and deepwater oil and gas puts forward higher requirements for drilling tools and instruments.This paper introduces the new developments in drilling tools and instruments abroad.Drilling tools include efficient rock breaking bits(Aegis armor cladded bit,Crush&Shear™hybrid bit,adjustable smart‑bit,StrataBlade concave diamond element bit and HyperBlade hyperbolic diamond element bit),auxiliary rock breaking tools(Navi-Drill motor;NitroForce®high‑torque,high‑flow motor and 300℃-resistant positive displacement motor)and circulating subs(iCWD intelligent circulation drilling tool,IDisc intelligent circulation and disconnection tool,MOCS G2 circulation sub and JetStream®RFID circulation sub);drilling instruments include rotary steerable tools(Lucida advanced‑rotary‑steerable tool,RST rotary steerable tool,VectorEDGE rotary steerable system,HALO high‑performance rotary steerable system and NeoSteer at-bit steerable system)and MWD(TruLink high definitive dynamic MWD,IriSphere look‑ahead LWD,HEX 200℃high temperature LWD and QuestTM gyro while drilling).On this basis,the future development of domestic drilling tools and instruments is suggested.Finally,it is pointed out that China should complete the localization of core drilling tools and instruments as soon as possible,and continue to strengthen the research on low‑cost alternative technologies to achieve economic and effective development.
