摘要(Abstract)：

根据储层地化分析、全岩X线衍射实验,以及二氧化碳、氮气等温吸附、聚焦离子束扫描电子显微镜等实验,分析渝东地区牛蹄塘组页岩的矿物组成、微纳米孔隙类型及其孔径分布特征。结果表明:渝东地区牛蹄塘组页岩微纳米孔隙类型包括有机质孔和无机质孔,其中无机质孔孔径相对较大,有机质孔孔径相对较小,不利于页岩气的赋存和有效渗流。牛蹄塘组页岩孔体积的14.53%由微孔提供,85.47%由介孔提供;孔比表面积的51.93%由微孔提供,48.07%由介孔提供。过高的有机质热演化程度和较差的保存条件是制约研究区牛蹄塘组页岩勘探开发的主要因素,勘探目标应以距大断裂较远、保存条件较好、热演化程度相对适中的地区为主。
