摘要

摘要: 页岩气主要以游离气和吸附气的形式存在于富含有机质的泥页岩中。目前，国内外在干酪根和黏土矿物对甲烷吸附能力的差异性研究方面还比较薄弱。由此提出了将干酪根和黏土矿物进行分离的方法，对干酪根和不同黏土矿物分别进行等温吸附实验，研究单位质量的干酪根、伊蒙混层、高岭石、绿泥石和伊利石对甲烷吸附能力的差异性。结果表明：对甲烷吸附能力大小的次序为干酪根> 伊蒙混层> 高岭石> 绿泥石> 伊利石，有些样品干酪根吸附气量大于黏土矿物之和的吸附气量。随着温度的升高，干酪根和黏土单矿物对甲烷分子的吸附量有所下降。在同一温度下，干酪根吸附气量随镜质体反射率增大而增加，黏土矿物基本不受镜质体反射率的影响。

Abstract: Shale gas mainly occurs in organic-rich shale in the form of free gas and adsorbed gas. At present, domestic and international research on the adsorption capacity of kerogen and clay minerals to methane is still relatively weak. A method for separating kerogen and clay minerals was proposed in this paper. The difference of adsorption capacity of methane in a unit mass of kerogen, illite mixed layer, kaolinite, chlorite and illite were studied by isothermal adsorption experiments on kerogen and different clay minerals. The experimental results indicated that the order of methane adsorption capacity is kerogen>illite mixed layer>kaolinite>chlorite>illite, and the gas adsorption capacity of kerogen in some samples is greater than the sum of that of clay minerals. The methane adsorption capacity of kerogen and clay single minerals decreases with temperature. At the same tempera-ture, the methane adsorption capacity of kerogen increases with vitrinite reflectance (R_o), while clay minerals are not affected by vitrinite reflectance.
