以巢北二叠系孤峰组（P2g）、龙潭组（P3l）和大隆组（P3d）页岩为研究对象，运用压汞和扫描电镜实验手段对页岩的孔隙结构进行分析。认为三组地层的主要孔隙类型为过渡孔，孔径范围在15.9～27.2nm 之间，孤峰组和龙潭组页岩的孔隙度为14.05%和13.47%、比表面积为13.722m2/g 和14.046m2/g、孔容为0.087ml/g 和0.067ml/g，均较接近。大隆组页岩孔隙度为1.58%，比表面积为2.16m2/g，孔容为0.008ml/g。样品的镜下 SEM-SE 图像可观察到孔隙类型以粘土矿物颗粒间孔隙为主，孔隙形状不规则，存在微裂缝。

With Permian Gufeng Formation(P2g),Longtan Formation(P3l)and Dalong Formation(P3d)in the Chaobei ar-ea as research subject,this paper made an analysis of pore texture of shale by means of mercury intrusion and scanning electron microscope(SEM)and concluded that the major pore type of the three formations is transitional pore in a range of 15.9nm to 27.2nm in size. Gufeng Formation and Longtan Formation have shale porosity respectively as 14.05% and 13.47%,specific surface area 2.16m2/g and 14.046m2/g,pore space 0.087ml/g and 0.067ml/g,all close to each other. Dalong Formation shale porosity is 1.58%,specific surface area 2.16m2/g and pore space 0.008ml/g. SEM-SE image of samples shows that clay mineral inter-particle pore is dominant,pore form is irregular and micro crack exists.
