摘　　要：通过对研究区取芯资料做一系列室内实验,对该区长6储层进行了岩石类型分析.结果表明储层砂岩的主要类型是以细粒长石砂岩为主,并含有中-细粒长石砂岩,经过对本区储层物性与孔隙结构特征研究,发现研究区目的层的孔隙类型主要是残余粒间孔和粒间溶孔以及溶蚀填隙物内孔隙[1].此外,通过研究分析本区和邻区资料与测试数据[2],将顾屯区长6油层孔隙结构划分为五种类型.Through a series of indoor experiments on the coring data in the study area,the rock type analysis of Chang 6 reservoir in the area shows that the main type of reservoir sandstone is fine-grained arkose and contains medium to fine-grained arkose.Through the study on the physical properties and pore structure characteristics of the reservoir in this area,it is found that the pore types of the target layer in the study area are mainly residual intergranular pores,intergranular dissolved pores and pores in the dissolution filler.In addition,by studying and analyzing the data and test data of this area and adjacent areas,the pore structure of Chang 6 reservoir in Gutun district is divided into five types.
