摘　　要：中国“山地式”页岩气的勘探开发与美国、加拿大等“平原式”页岩气勘探开发在地下地质构造上存在着极大差异,主要表现为页岩层内构造变形-变位复杂、勘探“甜点”认识不清、生产开发钻井过程中水平井段目标靶体寻找困难并时常出现工程事故等问题。本文从野外调查、岩心观察、钻井测井资料分析、地震剖面处理解释等方面分析总结了页岩气层内构造变动的研究方法与理论,在初步应用过程中已取得良好成效,能够有效识别页岩气层内构造变动。In the exploration and development of shale gas,there are great differences between“mountain type”shale gas in China and“plain type”shale gas in the United States and Canada in underground geological structures.In fact,the geological structure of“mountain type”shale gas in China is characterized by complex structural deformation and displacement in shale rock,which leads to unclear understanding of exploration“sweet spot”,difficulty in finding targets in horizontal well section and frequent engineering accidents during production and development drilling.In this paper,methodologies and theories are proposed for“mountain type”shale gas exploration in China,which provides a view for solving the basic theoretical and practical problems in production and development,and also provides scientific and theoretical guidance for efficient,safe,sustainable,and stable development of shale gas.
