摘要
利用野外露头、有机地球化学等资料,分析湘西北地区下寒武统牛蹄塘组页岩气资源勘探远景。初步研究表明,该地区下寒武统牛蹄塘组泥页岩有机质含量丰富、有机质类型好、热演化程度高,多数己达到成熟——过成熟阶段,是有效的页岩气烃源岩,可以作为今后页岩气勘探的目的层位。
Based on the outcrop, geochemistry and so on, this paper analyzes exploration prospects of Niutitang formation of Lower Cambrian shale gas resource in northwestern Hunan region. The analysis indicates that these argillaceous rock and shale of Niutitang formation characterized by rich organic matter content, fine kerogen type and high thermal evolution （mature to overmature） are valid source rocks of the shale gas, and will be the main object in future exploration of shale gas.
