Shale Gas Drilling and Completion Matching Technology of Zhongyuan Engineering Company
Abstract:With the efficient exploration and development of Fuling Shale Gas Field annual production capacity of 10 billion square meters and Changning-Weiyuan National Shale Gas Industry Demonstration Zone, Chinese energy structure is also constantly changing. The commercial development of shale gas depends on the continuous progress of cluster horizontal well drilling technology and large-scale fracturing technology. Efficient matching technology for drilling and completion is a powerful guarantee for shale gas improving the exploration and development. Sinopec Zhongyuan Petroleum Engineering Co., Ltd. has made a series of technological breakthroughs in drilling practice via independent tackling key problems, integrated matching, exploring new drilling techniques and tools. It has formed three-dimensional large offset long horizontal section horizontal well trajectory control technology, oil-based emulsification/soil-free oil-based drilling fluid technology, leakage prevention and plugging technology, shale gas interpretation and evaluation technology while drilling, oil-based drilling fluid high-efficiency flushing technology, zipper fracturing technology in Pad wells and high-pressure electrical network supporting engineering technology etc. More than 140 wells adopt above technologies in Fuling, Changning Weiyuan, Yongchuan and other Sichuan-Chongqing work areas, which effectively supported the shale gas productivity construction in China. This paper is a comprehensive summary of shale gas drilling and completion matching technologies based on technical research and practical drilling experience. It has a strong guiding significance for drilling and completion projects in other shale gas blocks.
