【摘要】：对渝东北城口地区下寒武统鲁家坪组页岩的地球化学特征、岩石矿物学特征、储集层物性特征、储集空间特征、含气性和保存条件以及页岩含气性的影响因素进行了分析后认为,研究区鲁家坪组页岩保存条件良好,有机质含量高,成熟度高,干酪根以Ⅰ型为主,页岩脆性高;储集空间以矿物粒间孔隙为主,储集层大孔较发育,单位吸附气量大,但由于渝东北城口地区鲁家坪组地层结构复杂,有机质成熟度过高,这些不利因素可能会加大后期开发的难度。
[Abstract]:The geochemical characteristics, petromineralogical characteristics, reservoir physical properties and reservoir spatial characteristics of the Lower Cambrian Lujiaping formation shale in Chengkou area, northeastern Chongqing, are discussed. It is concluded that the shale of Lujiaping formation in the study area has good preservation conditions, high organic matter content, high maturity, high kerogen type 鈪，
