摘要： 沾化凹陷古近纪沙二上-东营组沉积期处于断坳转换期。综合分析认为可将其划分为3个长期旋回和6个中期旋回,发育冲积扇、河流、三角洲、辫状河三角洲、扇三角洲、滨浅湖、滩坝、半深湖-深湖和湖底扇等各种沉积相类型。其中有利储集砂体的分布主要集中在C1、C2及C4旋回。沉积体系的分布受基底沉降、断层活动、物源区特征以及气候等因素的综合影响。

Abstract: The upper Sha'er-Dongying formation of Paleogene in Zhanhua sag is in period of fault-depression transform. The comprehensive analysis indicates that the formation could be divided into three long-term cycles and six middle-term cycles, in which nine sedimentary facies are developed such as alluvial fan, river, delta, braided river delta, fan delta, shallow lake, beach bar, semi-deep lake and deep lake and sublacustrine fan. The favorable reservoir sand bodies mainly distribute in C1, C2 and C4 cycles. The distributions of sedimentary systems are influenced by basal settlement, fault activity, provenance and paleoclimate, etc.

Key words: Zhanhua sag, falult-depression transform period, sequence stratigraphy, sedimentary response
