摘　　要：义东断裂带沙河街组的砂砾岩体油藏是沾化凹陷内重要的勘探类型,但因地震反射杂乱,制约了勘探进程。在综合分析义东断裂带的构造、沉积、岩相的基础上,结合砂砾岩的二维地震反射特征,认为该区砂砾岩体可划分为四期,以多期堆砌、无序沉积的小型近岸水下扇为主,地震反射多为空白或断续中弱反射。The glutenite reservoir of Shahejie form zone, Zhanhua depression. For the clutter seismic is an important exploration type in Yidong fault reflection of the glutenite body, the exploration process of glutenite reservoir is limited. Based on the comprehensive analysis of Yidong fault zone of tectonic, sedimentary, facies, combinate of 2D seismic that the region of glutenite body can be divided into reflection characteristics of glutenite, considered 4 stage, and small nearshore subaqueous fan is main deposition in which seismic reflection is blank or intermittent weak reflection. All of the future reflects the characteristics of small-scale inshore subaqueous fan deposition, multi period stacking disorder
