摘要
义正一吴堡区位于鄂尔多斯盆地中部，延安组是一套在延长组古侵蚀面上形成的网状～曲流河沉积。本文着重讨论了义正～吴堡延安组延9～延10储层物性的分布以及与沉积微相的关系、储层的分类、不同类型储层的孔隙结构和物性特征之间的关系。研究结果表明：储层渗透率的分布严格受沉积微相和岩相的控制；不同岩相的储层物性相差很大，对应着不同的储层类型；渗透率与孔隙结构密切相关。
Yizheng--WUbu oil fieldis located in the midile of the shan gan ning basin,the braided and meandering riverdeposiotion of yan-an formation is overlying on the old erosion surface of yan-chang formation,the area is characterized by apparent mark 1 ayers and recycle,main pay zones are Y9-Y10 members. The relation between the distribution of prosity and permeability and sedimentary miero-facies, classifications of reservoir and relations between pore structure characteristic and physical property are mainly discussed in the paper.
