摘要
The Chenjia fault is located in the middle part of the western Liaohe depression in Bohaiwan basin.It is a branch of the Taian-Dawa fault which is a major fault of western depression.In the thesis,the Chenjia fault is considered to be a two-step inverted fault based on the analysis of regional geological surveying in combination with the high resolution three-dimensional seismic data,well data,seismic profile and so on.The Chengjia fault experienced the compression in E2s3L～E2s3M,the extension in E2s3M～E2s3U,and compression in E2s3U～N1g.It is beneficial to the generation,migration,and accumulation of oil and gas.
