The pore character of fragmental reservoir is the principal research, which is not only widely used in the development of oil and gas exploration, but also in fine description of hydrocarbon-bearing pool and comprehensive evaluation of reservoir. The paper researches the pore types, texture and others of the reservoir of Lianggaoshan group in Central Sichuan basin. There are six mainly pore types,which include primary residual intergranular pore, secondary intergranular emposieu, intragranular emposieu, matrix pore, intercrystal pore and microcrack, in the region of the reservoir of Lianggaoshan group. The pore texture could be divided into two types marked as curve A and curve B. Curve A stands for the favorable reservoir type of Lianggaoshan group. The characters of curve B are contrary to A.%碎屑岩储层的孔隙特征是油气藏精细描述、储层综合评价的重要内容。通过对川中地区凉高山组储层的孔隙类型及孔隙结构的研究。将研究区凉高山组储层孔隙类型划分为原生残余粒间孔、次生粒间溶蚀孔、粒内溶孔、杂基内溶孔、晶间孔和微裂缝；将孔隙结构归纳为a、b两种类型，a型曲线代表凉高山组较为有利的储层类型，b型曲线特点则相反。
