摘　　要：以岩心分析化验资料为主，通过压汞、扫描电镜、铸体薄片、含油薄片及孔隙图像分析，深入探讨了曙２２块杜家台油层的微观非均质性．曙２块杜家台油层粘土矿物含量较高，粘土矿物成分以伊蒙混层为主，孔隙类型主要有粒间孔隙、溶蚀孔隙．孔隙结构分为三大类：高渗大孔细喉型，中渗大、中孔细喉型，低渗中孔细喉型．其中以中渗大、中孔细喉型为主．According to the data of core analysis as the major information, we have studied the micro heterogeneous of Dujiatai reservoir of Shu 22 blocks through the analysis of mercury injection ,SEM, thin section of cast mold, oil bearing thin section and pore image. The clay mineral content of the reservoir is high and its main components are mixed layer of illite and montmorillonite. Intergranular pore and vugular solution pore are the major pore type, and the large or middle pore with moderate permeability and fine throat is the important type of the pore structure.
