利用薄片等岩心化验测试资料,分析认为储层岩性以不等粒砂岩为主,砂岩类型以长石质岩屑砂岩为主;储层属于高孔高渗-特高孔高渗储层,孔隙类型以原生孔隙为主,喉道以中喉为主.依据有效厚度、孔隙度、渗透率等参数将该区储层分为Ⅰ类、Ⅱ类和Ⅲ类储层.通过对储层特征的研究,为油气区的下一步精细开发、深入开发提供重要的地质依据.%Based on the analysis of core observation,we studied the reservoir characteristics of D block of Xinglongtai oil layer. The results showed that the reservoir rock was mainly composed of feldspathic lithic sandstone, and the reservoir belongs to the high porosity-high penetration and special high porosity-high penetration type. The main pore type is primary pores and the throats mainly consist of medium throat. Comprehensive analysis showed that the reservoir can be classified into three types, i.e. the best reservoir(Ⅰ), common reservoir(Ⅱ) and poor reservoir(Ⅲ). It provided important geological theoretical basis for advanced development.
