摘要: 中国页岩气地质资源丰富,但与北美相比具有地质年代老、埋深大、热演化程度高、构造和地表条件复 杂的特点,很难实现商业开发。自2006 年以来,中国石化页岩气勘探开发经历了调研及选区评价、勘探突破和勘探 开发快速发展三个阶段。2012 年,海相页岩气勘探获得重大突破,高效建成中国首个页岩气田——涪陵页岩气田, 并实现威荣深层页岩气商业开发及其他勘探领域的不断拓展,页岩气探明储量、产量快速规模增长。经过十余年的科 技攻关和重大装备研发,中国石化创新引领了页岩气藏精细描述及综合评价技术体系,发展了立体开发调整技术,形 成了山地条件下优快钻井与长水平井分段压裂及气田绿色开发配套技术。中国石化未来将持续加强地质评价与探索, 夯实可持续发展的资源基础,坚持地质工程一体化发展思路,加强技术装备升级,利用大数据、人工智能助推油气行 业降本增效,加强项目全过程一体化管理,提升页岩气开发效益,从而实现中国石化页岩气探明储量、产量稳步增长。

Abstract: China is rich in geological shale gas resources. However, when compared with North America, these resources are characterized by greater geological age, deep burial depths, and high degrees of thermal evolution, as well as complex structures and surface conditions. It is therefore very challenging to achieve commercial development of shale gas in China. Since 2006, Sinopec’s shale gas exploration and development has experienced three stages: investigation and favorable area selection and evaluation; exploration breakthrough, and rapid progress of exploration and development. In 2012, major breakthroughs were made in marine shale gas exploration, and the first shale gas field in China, the Fuling shale gas field, was efficiently established. The commercial development of deep shale gas in the Weirong block has been achieved, and other exploration areas continuously expanded. The proven reserves and production of shale gas have been increasing rapidly. After more than 10 years of scientific and technological research, and development of major equipment, Sinopec has innovatively pioneered a fine description and comprehensive evaluation technology system for shale gas reservoirs, developed a stereoscopic development adjustment technology, and formed a series of supporting technologies for optimized fast drilling and long horizontal well staged fracturing in mountainous areas, as well as green development of gas fields. In the future, Sinopec will continue to strengthen geological evaluation and exploration, consolidate the resource base for sustainable development, adhere to the development idea of geology- engineering integration, strengthen the upgrading of technical equipment, promote cost decreasing and benefit increasing in the oil and gas industry by using big data and artificial intelligence, emphasize the integrated management of whole projects, and improve the development efficiency of shale gas, so as to achieve a steady increase in shale gas proven reserves and production of Sinopec.
