摘要(Abstract)：

为了探讨黔西北地区五峰一龙马溪组富有机质页岩含气性特征和主控因素,对习页1井岩心进行系统采样,并做孔隙结构、矿物组成、有机质含量、成熟度测试、等温吸附、现场解析等实验分析。研究表明:页岩气发育的富有机质页岩段主要位于五峰组和龙马溪组的底部,岩性以黑色炭质页岩、钙质页岩和硅质页岩为主;黑色页岩具有较好的吸附能力,含气页岩层段以吸附气为主;页岩含气量与有机碳含量、比表面、总孔隙度等均具有较好的正相关关系,与黏土矿物含量具有负相关关系,游离气所占比例与有机碳含量、比表面、总孔隙度呈负相关关系。
In order to explore the gas-bearing property's characteristics and main controlling factors of WufengLongmaxi Formation shale enriched in the organic matters in Northwest Guizhou,the cores are sampled systematically in Well Xiye-1,and moreover the experimental researches on the pore structures,mineral compositions,organic matter contents,maturity test,isothermal absorption,and field analyses and so on are conducted.The studies show that the enriched organic matter shale intervals,in which the shale gas is well-developed,are mainly distributed in the bottom of Wufeng and Longmaxi Formations,the lithology is generally black carbonaceous shale,calcareous shale and siliceous shale;there is much better absorbing capacity for the black shale,the absorbed gas is mainly distributed in the above intervals;there are the positive correlations between the shale-gas contents and the TOC,specific surface area,total porosity and so forth,and there are the negative correlations with the clay mineral contents,there are the negative correlations between the free-gas proportions and the TOC,specific surface area,total porosity.
