摘　　要：城华斜坡带油田位于陕甘宁盆地南端 ,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 ,该区的主要油组是延 8～延 10。着重讨论了城华地区延安组延 8～延 10储层渗透率非均质程度、引起强非均质性的主要原因、渗透率非均质性与沉积微相的关系以及非均质性和注采的关系。Cheng Hua slope oil field locats in the south of the Shanganning basin,draidedbeander river deposition of Yan'an Group overlying on the fossil erosion surface of Yanchang group,the main oil Group is Y8～Y10 in this areas.It is mainly discussed the heterogeneous degrees of permeability,reason of causing reservoir heterogeneous,and the relationship between permeability heterogeneous and sedimentary microfacies.
