摘　　要：元坝气田是国内埋藏最深的海相大气田,其存在气藏埋藏深、酸性气体含量高、压力层系多、地层岩性复杂等世界级钻井技术难点。文章在对元坝超深高酸性气田钻井技术难点分析的基础上,介绍了井身结构优化技术、空气钻井技术、扭力冲击器钻井技术等关键提速技术和钻井液性能维护、套管防磨、井控等安全管理措施及其应用效果,最后给出了元坝地区超深高酸性气田的钻井提速技术系列。Yuanba gas field is the largest marine gas field in our country, however there are many drilling difficulties in this region, such as its gas reservoir is very deep, acid gas content is high, formation pressure and lithology is complex and so on. This paper focuses on introducing the key drilling technology to increase drilling speed and their application on the basis of analysis for the drilling difficulties for Yuanba region, such as optimization technology for well structure, air drilling technology, torque impactor drilling technology, maintenance of drilling fluid properties, decrease casing wear technology and well-control. Finally this paper proposes a series of increasing drilling speed technology.
