摘要

伊朗Y油田含油层系Sarvak组油气储集层主要为富含蛤类化石的白垩质灰岩,储集空间类型主要为孔隙和洞,为中孔低渗—特低渗型储层。沉积环境为浅海碳酸盐岩台地边缘斜坡及礁边缘相。储层层内相对均质,而层间非均质性严重。优质储层受沉积环境和成岩作用双重因素控制,发生白垩化成岩作用较强的碳酸盐岩台地前缓坡相和台地浅滩相是白垩质灰岩储层发育的有利相带。Sarvak组油藏类型为层状边水油藏,油水界面倾斜,开发中尽可能依托储层特征及油藏类型,增加开发效益。

Abstract

Reservoirs of Sarvak Formation in the Y Oilfield of the Zagros Basin,Iran are rich rudist-bearing chalky limestone.Reservoir spaces are mainly porosities and vuggs,with few fractures.The reservoirs were deposited in slope of marginal neritic carbonate platform and marginal reefs.The heterogeneity in intralayer is weak while strong in interlayer.In charge of sedimentary environment and diagenesis,high-quality reservoirs developed in slope of marginal neritic carbonate platform and marginal reefs which with slightly chalk-diagenesis.Sarvak Formation is a multi-layer stacked reservoir with weak edge water and a tilted oil-water contact.Development must depend on reservoir characteristics and reservoir types.
