中文摘要：

基于对惠民凹陷和东营凹陷沙四上亚段滩坝相的解剖研究成果，提出了适合这2个地区滩坝沉积体研究的分类方案。通过对勘探研究程度较低的惠民凹陷和勘探研究程度较高的东营凹陷滩坝沉积特征的对比分析，明确了惠民和东营凹陷沙四上亚段滩坝的沉积特征和展布模式受可容纳空间、湖平面升降与古岸线变迁、沉积水动力转换带、物源、古地貌及地层坡度等因素的控制。其中，起主要作用的是构造运动对凹陷形成所造成的沉积地形上的差异性、物质供给来源以及沉积水动力对滩坝砂体空间分布的控制。滩坝相的2种空间分布模式：东营凹陷单断单超水下低隆型滩坝分布模式和惠民凹陷中央隆起型滩坝分布模式。

英文摘要：

Bring up a classification scheme suit foranalyzing beach bars sedimentary system basin based on Upper Es4 in Huimin and Dongying depression. Through comparison and analysis of beach bars sedimentary characteristics, the sedimentary characteristics and distribution model of beach bars are controlled by accommodation space, lake level fluctuation, ancient shoreline change, sediment dynamics transfer zone, provenance, palaeogeomorphology and strata gradient. Sedimentary terrain differences caused by tectonic movement,provenance and sediment dynamics transfer zones play a major role in the factors. Two kinds of spatial distribution model about beach and bar sedimentary facies are summarized, a model for the facies in single fault overlap and middle rise of Dongying depression, and another model for the facies in centralrise of Huimin depression.
