摘　　要：通过对苏里格气田Z30区块二叠系山西组山1段及石盒子组盒8段储层岩石学特征、物性特征以及微观孔隙结构特征进行分析,发现研究区山1段及盒8段储层表现为明显的低孔低渗特点。孔隙类型有原生孔隙、次生孔隙、微裂隙,次生孔隙以溶蚀粒间孔为主。根据物性及压汞曲线特征参数将储层分为4类,其中Ⅱ类、Ⅲ类储层所占比重最大。研究认为,物源、沉积环境、成岩作用、裂缝等是决定储层特征的控制因素。Through the analysis of characteristics of petrology, reservoir property and micro-pore structure of Shan-1 and He-8 of permian reservoirs in the Z30 area in Sulige Gas Field,it is found that Shan-1 and He-8 reservoir is of obvious low-porosity and low-permeability; the pore types include primary porosity, secondary porosity and micro cracks;the secondary porosity is mainly solution intergranular. According to physical properties of reservoirs and parameters of pore structure,reservoirs in this area can be divided into four types, which are dominated by type II and type III. It is concluded that sediment provenance, sedimentation,diagenesis and microeraeks are controlling factors of reservoirs feature.
