| 摘 要： | 应用先进技术与方法，对取自该地区的典型二叠系岩芯样品，进行了系统的地球化学、矿物组成、孔隙度及孔隙结构等方面分析。结果表明，这套二叠系烃源岩孔隙发育，平均孔隙度可达5.37%；纳米级孔隙发育，并以微孔和介孔为主；泥页岩总有机碳含量（TOC）和黏土矿物含量是控制吸附能力和孔隙大小的关键因素。二叠系富有机质泥页岩孔隙度较高，发育大量的纳米级孔隙及具有较大的比表面积，为页岩气储存提供了良好条件。

| Abstract: | In this study，advanced technologies were applied to investigate the geochemistry，mineral compositions，porosity and pore structures of the Permian shale core samples from this area.The results show that the Permian source rocks have an average porosity up to 5.37% and the nanoscale pores are mainly developed as micro- and meso-pores.The total organic carbon(TOC) content and clay mineral content of the shales are key factors to control gas adsorption capacities and pores sizes.The well developed nanopores and large surface area in the Permian organic-rich shale could provide good conditions for shale gas storage. |
