摘要
通过地表露头、地质和地球化学资料的分析,认为城口区块上奥陶统五峰组和下志留统龙马溪组页岩具有高有机碳含量、高过成熟度、节理裂缝发育、具有储藏页岩气的条件、解析(等温吸附)气含量高;根据地表的化验结果,预测了远景区;结合地貌指出了具有开发条件有利区。
Geological and geochemical study indicates that shale of the Upper Ordovician Wufeng Formation and the Lower Silurian Longmaxi Formation in the Chengkou area is characterized by high organic carbon content, high/over mature, developmental crack and fissure as well as high resolution(isothermal adsorption) gas content. This paper predicts perspective of shale gas in the Chengkou area.
