摘　　要：盐定地区长8～长9岩屑组分主要以岩屑长石砂岩为主,粒度总体呈从上至下变粗,储层胶结物类型较多。储层物性主要以中孔低渗-特低渗为主。沉积微相、岩性特征、胶结物及孔隙类型是影响储层物性的主要因素。通过对盐定地区长8～长9储层孔隙度、渗透率、砂岩厚度、成岩作用等参数的分析,建立了盐定地区长8～长9储层评价标准,在此基础上,对盐定地区长8～长9储层开展了储层评价工作。Salt given area Chang 8-Chang 9 lithic overall was top to bottom, thicker, more the type component lithic arkose main particle size of reservoir cements. Reservoir properties, porosity and permeability-low permeability. Microfacies lithology, cement, and pore types are the main factors affecting the reservoir properties. Salt given area long 8-the parameters of long reservoir porosity, permeability, thickness of sandstone diagenesis, salt given area Chang 8- Chang 9 reservoir evaluation criteria, and on this basis, salt given areaChang 8-Chang 9 reservoir to carry out reservoir evaluation.
