国内外钻完井技术新进展

页岩气、致密油/页岩油、致密气、深水、极地等的勘探开发活动推动了全球钻完井活动持续回升，促进了水平井、工厂化作业等钻井技术，以及快速移动钻机、深水钻机、极地钻机等钻井装备的快速发展。国外近年来在高效起下钻机和高运移性钻机，复合钻头、微芯钻头及高效辅助破岩工具，井下实时大容量信息高速上传，实现造斜段和水平段一趟钻的高造斜率旋转导向技术，可折叠连续管，钻井远程传输与实时优化，连续循环系统，控压钻井，高温油基钻井液、新型水基钻井液和新型堵漏技术等方面取得显著进展。国内在万米钻机及配套装备、MWD/LWD/EMWD/近钻头地质导向系统、连续管技术与装备、控压钻井、垂直钻井、随钻温度压力测试等方面也实现重要突破，推动了钻井技术与装备不断进步。

Advances in well drilling and completion technologies for domestic and overseas

The exploration and production of shale gas, as well as tight oil/shale oil, tight gas, deep water and arctic hydrocarbon, is promoting global drilling and completion activity to continuously rebound, which boosts the rapid development of drilling techniques such as horizontal well, factorial construction, and drilling equipment including quick-carrying drilling rigs, deep-water drilling rigs, and polar drilling rigs. Foreign corporations have made substantial progresses on high effective round trip drilling rigs, quick-carrying rigs, cone/PDC complex bits, micro-coring bits, high effective rock-breaking tools, downhole real-time high capacity information transmission, high build-up rate rotary steerable system （buildup section and horizontal section drilled in one run）, fold coiled tubes, drilling remote information transmission and real-time optimization, continuous circulation system, managed pressure drilling, high temperature oil base drilling fluids, new type water base drilling fluids, new type sealing technologies, etc. Domestic corporations have made a significant breakthrough in myriameter rig and auxiliary devices, MWD/LWD/EMWD/CGDS, coiled tube technologies and equipments, CPDS managed pressure drilling system, vertical drilling system, temperature and pressure test while drilling and so on, which promotes drilling technologies and equipments to get ahead quickly.
