摘要
页岩气作为一种重要的非常规油气资源,资源潜力巨大,已经在北美地区取得商业开发成功,中国正在积极寻找页岩气勘探有利区并争取实现页岩气商业开发。储层研究是页岩气勘探初期的主要研究任务,对准确寻找有利区具有重要的现实意义。通过对国内外相关文献整理分析,概述了页岩气成藏机理、成藏过程及赋存状态,并对页岩气储层研究中的矿物组成、有机地球化学特征、物性特征、储集空间、含气性特征等方面的评价方法与标准进行了系统的总结。最后,探讨性指出页岩气储层研究中存在的问题及解决问题的关键。
As a kind of major unconventional resources,shale gas has a huge potential. It has been successfully developed in North America. Currently,China is striving to seek for favorable shale gas areas in commercial level. Research on shale gas reservoir is the major task at the initial stage of shale gas exploration,which is of great significance to the accurate identification of favorable areas. Through processing and analysis of literatures at home and abroad,this paper describes the reservoir-forming mechanism,reservoir-forming process and occurrence of shale gas. The evaluation approach and standards of mineral compositions,organic geochemical features,physical property features,reservoir space,and gas-bearing features in the research on shale gas reservoir are systematically summarized. Finally,existing problems in the research on shale gas reservoir and potential solutions are discussed.
