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,该区标志层明显,旋回特征清晰,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储层孔隙度和渗透率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。

Abstract:

Cheng-hua slope oil field is located in the south of the shan gan ning basin, the braided and meandering river deposition of yan-an formation is overlying on the old erosion surface of yan-chang formation, the area is characterized by apparent mark layers and recycle, main pay zones areY8-Y10members. The relation between the distribution of prosity and permeability and sedimentary micro-facies, classifications of reservoir and relations between pore structure characteristic and physical property are mainly discussed in the paper.

Key words: reservoir characteristics, reservoir physical property, sedimentary micro- facies, lithofacies, Yan- An formation reservoir
