| Abstract | P58; 目的 为了解煤系页岩中孔隙结构特征及其演化规律,方法 采用X射线衍射、岩石热解、扫描电镜、低压CO2/N2吸附和高压压汞等实验,对鄂尔多斯盆地东缘山西组煤系页岩不同岩相孔隙结构进行表征,分析成岩作用对各岩相孔隙演化的影响.结果 结果表明,山西组主要发育富硅泥质页岩岩相(A-1)、泥质/硅质混合页岩岩相(M-2)和富黏土硅质页岩岩相(S-3);介孔是储层孔容的主要来源,贡献度达65%以上,微孔是储层比表面积的主要来源,贡献度达62%以上;S-3页岩总孔容和总比表面积均较大,均值分别为0.036 2 cm3/g,35.15 cm2/g,A-1页岩总孔容和总比表面积均较小,均值分别为0.026 6 cm3/g,21.39 cm2/g;有机质通过控制微孔发育对页岩比表面积起控制作用,另外,黏土矿物对页岩比表面积有一定促进作用,黄铁矿对M-2页岩和S-3页岩孔隙结构均有一定促进作用;A-1页岩孔隙演化受压实作用、黏土矿物转化作用最为明显,S-3页岩孔隙受胶结作用、有机质生烃作用和溶蚀作用影响均较显著,M-2页岩孔隙兼具A-1和S-3页岩的成岩演化特点.结论 研究结果可为鄂尔多斯盆地煤系页岩孔隙结构研究提供借鉴与参考. |

| Abstract_FL | Objectives In order to clarify the development and evolution laws of pores structure in coal-measure shale,Methods this study used X-ray diffraction,rock pyrolysis,scanning electron microscope,low-pressure CO2/N2 gas adsorption and high-pressure mercury intrusion experiments to characterize the pore structure of various lithofacies in Shanxi Formation coal-measure shale in the eastern Ordos Basin.Results The research shows that the Shanxi Formation mainly develops silica-rich argillaceous shale lithofacies(A-1),siliceous/argillaceous mixed shale lithofacies(M-2),and clay-rich siliceous shale lithofacies(S-3).Meso-pores are the main origin of pore volume,with a contribution of more than 65%,while micropores are the main origin of reservoir specific surface area,with a contribution of more than 62%.The total pore volume and total specific surface area of the S-3 shale are larger,with an average value of 0.036 2 cm3/g and 35.15 cm2/g,respectively,while the total pore volume and total specific surface area of the A-1 shale are smaller,with an average value of 0.026 6 cm3/g and 21.39 cm2/g,respectively.Organic matter controls the specific surface area of the shale by controlling the development of micropores.In addition,Clay minerals have a cer-tain positive effect on the specific surface area of the shale,while pyrite has a certain promoting effect on the pore structure of M-2 and S-3 shale.The pore evolution of A-1 shale is most obviously affected by com-paction and clay mineral transformation,while the pores of S-3 shale are significantly influenced by cemen-tation,organic hydrocarbon generation and dissolution.The pores of M-2 shale exhibit both the diagenetic evolution characteristics of A-1 pores and S-3 shale.Conclusions The research results can provide refer-ence and guidance for the study of pore structure of coal-measure shale in the Ordos Basin. |
