通过对高集油田阜宁组钻井岩心观察、铸体薄片鉴定以及测井资料分析，确认该组储层以湖相碳酸盐岩为主。结合该区物性特征和铸体薄片资料，对该区储层沉积相、岩石类型、孔隙类型等基本特征进行研究。结果表明，研究区储层集中分布于阜二段的生物碎屑灰岩和鲕粒灰岩。在Choquette和Pray提出的孔隙空间成因分类体系基础上，对该区孔隙进行分类研究，并对影响储层发育的主要因素——沉积相和成岩作用进行了概括总结。

Based on the drilling core observation, casting thin section identification and logging data analysis of Funing Formation in Gaoji Oilfield, the lacustrine carbonate reservoir is determined as the research object. Combined with the physical property characteristics and casting thin section data, the sedimentary faces, rock type, pore type and other basic features of reservoir in this area are studied. The result shows that the reservoirs mainly distribute in Fu 2 Member bioclastic limestone and oolitic limestone. On the basis of pore space genetic classification system which is put forward by Choquette and Pray, the pore type classification in study area is also analyzed and the major factors influencing reservoir development, including sedimentary faces and diagenesis, are summarized.
