摘要: 为了研究湘中坳陷二叠系龙潭组和大隆组黑色页岩的吸附能力及其控制因素,开展了全岩矿物含量分析、有机地球化学分析、储层物性分析和等温吸附实验研究。结果表明:①页岩主要为硅质页岩,石英质量分数平均为34.4%,且多为生物成因硅,黏土矿物质量分数平均为24.4%,矿物组分特征与美国Barnett页岩和四川盆地古生界优质海相页岩类似。②页岩中干酪根类型以Ⅱ2型为主,处于成熟阶段,有机碳质量分数平均为2.63%,有机质孔发育,主要为微孔和中孔。③页岩吸附能力较强,饱和吸附质量体积为0.75~8.60 m3/t,平均为4.51 m3/t,具有良好的甲烷吸附能力。④页岩吸附能力主要受控于有机碳含量、氯仿沥青"A"、总烃、石英含量、岩石密度和孔隙结构。其中,有机碳含量对页岩吸附能力的影响最为显著。湘中坳陷海陆过渡相页岩具有较大的勘探潜力。
