摘　　要：利用岩心资料以及扫描电镜、黏土矿物X衍射、高压压汞、有机包裹体荧光分析等分析化验资料,对研究区储层物性进行综合分析。结果表明:研究区长7储层以长石砂岩为主、长8储层以岩屑质长石砂岩为主、长9储层以长石质岩屑砂岩为主;胶结物以铁方解石为主。按成因类型可将长7~长10孔隙分为原生孔隙和次生孔隙两大类,主要为小孔中细喉道储层。根据孔隙度与渗透率的相关关系,说明该区储层主要为孔隙性储层,裂缝基本不发育。结合沉积微相、孔隙度、渗透率等参数对该区储层物性进行综合分析,得知好储层主要分布于水下分流河道,这为今后进一步勘探指明了方向。The characteristics of Chang 7-10 reservoir of Upper Triassic Yanchang Formation of Sui-Jing oil field are studied by core data and analysis and testing data, such as scanning electron microscope, clay mineral X diffraction, high pressure mercury injec- tion, and organic inclusion flurometric analysis and so on. The results show that the main lithology of Chang 7 reservoir of Sui-Jing oil field is feldspathic sandstone, Chang 8 reservoir is lithic arkose sandstone, Chang 9 reservoir to feldspathic lithic sandstone dominated ; cementation with iron calcites. According to the genetic types, the porosity types of Chang 7-10 can be divided into two types ： primary porosity and secondary porosity, with small throat channel. According to the relationship between porosity and permeability, porosity reservoir is the main type of Chang 7-10 reservoirs and the fracture is almost not developed. The reservoir physical properties are ana- lyzed in combination with the sedimentary mierofacies, porosity and permeability, it turns out that the good reservoir is mainly distribu- ted in the underwater channel, which indicates the direction for further exploration.
