摘　　要：以岩心分析化验资料为主，结合测井解释资料，探讨了曙２块杜家台油层储层的宏观非均质性．曙２２块杜家台油层是由多个扇三角洲前缘砂体叠加而成，受构造及沉积环境的控制，砂体发育程度、储层物性条件较差，储层物性参数中孔隙度值较高、而渗透率值较低，层间非均质性较弱，而平面及层内非均质性较强．According to the data of core analysis as the major information, combining the data of log interpretation, we studied the macro heterogeneity of Dujiatai reservoir of Shu 22 blocks. The reservoir is overlapped by several frontal sand bodies of fan deltas. Under the control of structure and sedimentary environment, the development extent of sand body and the physical property condition of the reservoir are poor. Among the parameters of physical property of the reservoir, the value of porosity is high while the value of permeability is low. The interlayer heterogeneity is weak while the plane and the intra layer heterogeneity are strong.
