摘要
This paper focuses on the analysis of geochemical indicators,shale reservoir characteristics,gas-bearing of sets of dark shale,and discusses the geological condition of the formation of Shahejie.It is believed that Shahejie lacustrine shale in Jiyang Depression is of great thickness of sediments with high abundances of organic matter and the main kerogen type is Ⅰ;the maturity of organic matter is from mature to high mature stage.The content of brittle mineral in shale of Bohai Bay Basin is high.Comprehensive analysis shows that lower the 3rd member of the Shahejie Formation is preferred layer of shale gas exploration and development.
