页岩气开发钻完井技术探讨

Complete Drilling and Completion Technology for Shale Gas Development

摘要:

我国广泛分布着丰富的页岩气资源，开发应用远景良好。通过借鉴、转化、应用常规油气开发的成熟技术，可集成配套形成页岩气开发钻完井技术系列。水平井已成为页岩气开发的主要钻井方式，结合旋转导向、MWD/LWD、三维地震和欠平衡钻井等工艺技术的集成应用可提高开发效率。水力压裂工艺已成为页岩气开发的主要技术，随着清水压裂、重复压裂、同步压裂等技术的发展，页岩气的勘探开发更具发展潜力。

Abstract:

China is very rich in shale gas resources with great development potential. It is possible to form a series of complete drilling and completion technology for shale gas development through borrowing, converting and utilizing of wellproven conventional oil and gas development technology. Horizontal drilling has dominated the drilling methods for shale gas development, and integrated with rotary steerable drilling, MWD/LWD, 3-D seismic survey, and underbalanced drilling, it will increase development efficiency. Hydraulic fracturing is a main technique for stimulation of shale gas reservoirs. Advances in slick water fracturing, refracturing, synchronized fracturing, etc., will make shale gas development more promising.
