| 摘 要： | 通过对川东南地区志留系龙马溪组页岩有机质丰度、热成熟度、有机质类型、脆性矿物含量、页岩层厚度、埋藏深度、构造形态等七大地质因素的综合分析,认定该区分布广泛的页岩有机质含量较高,有机质类型较好,热演化程度高,生烃潜力大,具备形成页岩气藏的气源条件。页岩厚度较大,埋深较浅,脆性矿物含量较大,页岩气的保存条件良好,有利于页岩气的压裂与开采。

| Abstract: | Basing on the research of the source rock of south-eastern Sichuan area and 3D seismic exploration, by analyzing sample on the spot, we discuss the distribution and exploration potential of the Longmaxi formation＇s shale gas source rocks of lower Silurian. the article analysis and evaluates seven geological factors of this formation： organic matter abundance, thermal maturity, the type of organic matter, content of brittle mineral, thickness of shale, burial depth, structural shape, and make sure that the widely distributed shale of Longmaxi formation possesses being gas source condtions of forming shale gas reservoir finally： high content and good type of organic matter, high levels of thermal evolution, high potential of hydrocarbon generating, meanwhile, thick shale formation, shallow buried, and high content of brittle mineral and suitable preservation condition, all these factors are beneficial to fracturing and mining of shale gas. |
