Sedimentation and Geochemistery Features of the Organic-Riched Shale in Wufeng-Longmaxi Formation, West of HuNan-HuBei Province
Abstract: Hunan-Hubei region Wufeng-Longmaxi Formation is a thick layer of mud shale, according to its sedimentary characteristics determine the sedimentary types of clastic shelf, shallow surface canopy and deep surface shed further subdivided into Asia. Combined deposition and Earth chemical features analysis, indicates that: Wufeng-Longmaxi Formation Xia paragraph to ash black, and deep grey silicon mass page rock, and carbon mass page rock and pen stone page rock mainly, has continuity deposition, average thickness up50 maround, regional distribution stability, buried depth more shallow, TOC average up 1.33%, hot evolution degree higher, organic matter type to most to Ⅱ type mainly, is page rock gas development of enabling layer paragraph. River page 1 drilling confirms that the Wufeng-Longmaxi Formation has a certain set of gas-bearing. Geochemical characteristics of shale gas deposits, such as basic research, for shale gas exploration work in the area are of great geological significance.
