摘　　要：为进一步探明苏里格气田致密气储藏分析,通过岩心观察、SEM扫描电镜等方法对南部地区盒8段储层的岩层地质进行分析,结果表明在研究区域处在三角洲沉积区域区域,岩性以岩屑石英砂岩、石英砂岩、岩屑砂岩为主,在孔隙方面,以5%~10%特低孔为主,且孔隙类型以收缩缝和粒间孔-粒内溶孔-晶间孔为主。在孔隙主要成分中以方解石、高岭石等为主,由此通过盐化、交代和溶蚀形成高渗储层,说明该区域油气资源分布较广。In order to further explore the tight gas storage analysis of Sulige gas field,through core observation,SEM scanning electron microscopy and other methods to analyze the rock stratum geology of He8 member reser⁃voir in the south area,the results show that the study area is in the delta sedimentary area,the lithology is main⁃ly lithic quartz sandstone,quartz sandstone and lithic sandstone,in the aspect of porosity,it is mainly 5%-10%ultra-low porosity,and the pore types are mainly shrinkage cracks and intergranular pores-intragranular dis⁃solved pores-intercrystalline pores.Calcite and kaolinite are the main components in the pores,which form a high permeability reservoir through salinization,metasomatism and dissolution,indicating that the oil and gas re⁃sources in this area are widely distributed.
