Title: Characteristics of Organic-rich Shale and Exploration Area of Shale Gas in Guizhou Province
Abstract: It presented the marine environment at the long term geological time and formed the multi-sequence organic-rich shale under anaerobic deposition environment in the Guizhou province.Based on distribution and thickness of organic-rich shale,we divide into 7 organic-rich shale sequences,such as Sinian Doushantuo Formation,lower Cambrian Niutitang Formation,upper Ordovician Wufeng Formation,lower Silurian Longmaxi Formation,middle Devonian Guanziyao-Huohong Formation,lower Carboniferous Datang Formation,Permian Xixia-Longtang Formation.The shale gas source rocks in the Guizhou are characterized as multi-sequences,large thickness,high organic carbon content,and high thermal maturity.According to thickness and distribution of source rocks,organic carbon content and thermal maturity,we draw three favorable areas of shale gas exploration,i.e.Wuling fold,central-north Guizhou,and Ziyun-Ceheng of Nanpanjiang.The most favorable area of shale gas exploration in the Guizhou province is the Ceheng-Wangmo area in the Nanpanjiang basin.
