摘　　要：本文对大港枣园油田冲积扇储层进行了系统研究,重点为枣园油田枣北断块孔一段枣Ⅱ油组。经研究认为枣Ⅱ组为干旱环境下冲积扇扇中亚相,进一步划分为辫状河主河道沉积,辫状河次河道沉积,溢岸沉积及河道间洼地沉积。这些微相由不同沉积方式形成沉积物以不同组合类型构成,从而造成了不同微相形成砂体平面展布不同,砂体储层非均质性也不同。A systematic study has been made in this paper on Zaoyuan alluvial fan reservoir,especially on the north fault block of Zaoyuan oilfield,zone Zao Ⅱ, Kuongdian formation.It's identified that zone Zao Ⅱ is a kind of arid allu- vial fan deposits and belongs to the midfan subfacies.It can be further di- vided into main braided stream,subbraided stream,overbank and low-lying area of interstream.These microfacies are composed of different sediments in different composition formed by different deposition.Thus sandbodies for- med by different microfacies have different characteristics both in distribu- tion and reservoir heterogeneity.
