摘　　要：根据铸体薄片、物性分析及压汞曲线资料分析,对东胜气田锦30井区储层岩石学特征、物性及孔隙结构特征开展系统研究及分类评价。研究表明:该区盒1段储集砂岩岩性以(含砾)粗粒、中粒岩屑石英砂岩和石英砂岩为主;平均孔隙度8.8%、平均渗透率0.47mD,总体上属于特低孔、特低渗储层;孔隙类型主要为粒间余孔、粒间溶孔以及粒内溶孔;孔隙结构则以细孔-中小孔喉为主。Ⅰ类和Ⅱ类储层物性好、开发动用程度较高,是勘探开发的主要类型。According to the analysis of cast thin section,physical property analysis and mercury injection curve,the petrological characteristics,physical properties and pore structure characteristics of reservoir in well block Jin 30 of Dongsheng gas field are systematically studied and classified.The study shows that the reservoir sandstone lithology of He 1 member in this area is mainly coarse-grained,medium grained lithic quartz sandstone and quartz sandstone;The average porosity is 8.8%and the average permeability is 0.47md.Generally,it belongs to ultra-low porosity and ultra-low permeability reservoir;The pore types are mainly intergranular residual pore,intergranular dissolved pore and intragranular dissolved pore;The pore structure is mainly fine pore small pore throat.Class I and II reservoirs have good physical properties and high development degree.They are important reservoir types for exploration and development at present.
