摘要:

中国页岩气资源量丰富,但前期借鉴美国理论技术在中国寻找页岩气,并未取得大型商业发现。为此,中国石油化工股份有限公司立足自主创新,围绕中国海相页岩气地质特点,开展了理论研究和技术攻关。通过揭示页岩气"早期滞留,晚期改造"的动态保存机理,形成了"深水陆棚相优质页岩发育是页岩气'成烃控储'的基础,良好的保存条件是页岩气'成藏控产'的关键"的新认识;形成了以页岩气地球物理、开发设计与优化、水平井钻完井及压裂为主的页岩气勘探开发核心技术及关键装备,发现并成功开发了中国首个也是目前最大的页岩气田——涪陵页岩气田,使中国成为北美之外第一个实现规模化开发页岩气的国家。截至2017年8月,涪陵气田探明页岩气地质储量6 008.14×108m3,已建成76.8×108m3产能,累积产气量为133.9×108m3,并实现了清洁生产。气田高水平、高速度、高质量建设,是中国页岩气勘探开发理论创新、技术创新的典范,为中国页岩气勘探开发提供了可复制、可推广的经验,对优化能源结构、改善环境质量具有重要意义,走出了中国页岩气自主创新发展之路。

Abstract:

Although shale gas resources are abundant in China, commercial discoveries have not been made before the discovery of Fuling shale gas field. Sinopec has done lots of theoretical and technological studies on marine shale gas development in China. Research shows shale gas has dynamic accumulations with early preservation and late reconstruction and proposes high-quality shale developed in deep-water shelf as the base and good preservation conditions as the key factor for shale gas accumulation. Key technologies and facilities were developed for geophysical survey of shale gas, design and optimization of shale gas development, drilling and completion of horizontal wells, and fracturing stimulation. As the first and largest shale gas field in China, the discovery and successful development of Fuling shale gas filed has made China the first country to achieve large-scale development of shale gas after North America. By August 2017, Fuling shale gas field had declared 6 008.14×108m3 proven reserves, 76.8×108m3 production capacity and 133.9×108m3 cumulative production. The construction of Fuling shale gas field with high level, high speed and high quality has been a good example of shale gas development in China. Its successful experiences can be used to other fields and play an important role in optimizing energy structure and improving environment.
