摘要/Abstract

摘要： 复杂沉积环境下沉积相及其演化的准确描述可以有效地指导油气田的勘探和开发过程。结合东濮凹陷卫城油田的区域沉积背景，利用岩心描述、录测井和分析测试等资料对东濮凹陷卫城油田卫81区块沙河街组四段的沉积特征与沉积相模式进行了全面分析。结果显示：该区块地层发育末端扇-滨浅湖滩坝相过渡型沉积，沙四下段河流末端能量损失、流量波动，发育末端扇沉积，分流河道顺物源方向向河道漫溢和泥滩演化，形成扇状堆积体；随湖平面频繁大面积扩张收缩等沉积环境变化，沙四上段演化为滨浅湖滩坝沉积，滩坝砂体整体呈复合砂体连片平行于主控断层走向分布。

Abstract: The accurate description to sedimentary facies and its evolution of the complicated depositional environment can effectively guide the oil and gas field exploration and exploitation. Combined with the regional background of Weicheng structure in Dongpu depression, the depositional features and sedimentary model of the 4th member of Shahejie Formation (Es₄) in Wei 81 block of Weicheng oildfield were analyzed by use of the data of core description, logging, analysis and test, etc. It is considered that the associated sediments of terminal fan to beach-bar in shore-shallow lake are developed in the study formation of this block. The terminal fan was developed in the background of energy loss and flow fluctuation at the end of the rivers in the lower part of Es₄, and the distributary channel evolved into overflow or mudflat along the source direction,thus forming the fan-shape accumulation; with the change of sedimentary environment under the frequent expansion or shrink of the lake level, the beach-bar sediments in shore-shallow were developed in Es₄, paralleling to the trend of master fault with composite form.

Key words: associated deposits of terminal fan to beach-bar, sedimentary model, depositional evolution, sand distribution, Weicheng oilfield, Dongpu depression
