摘　　要：根据地质、测井及地震资料的综合分析,着重描述和分析东辛地区沙河街组三段滑塌浊积扇砂体沉积和发育特点,将本区的滑塌浊积扇砂体划分出了3种沉积微相,建立了砂体垂向序列和分布模式,进而说明了滑塌浊积扇砂体发育的地区性控制因素。认为东辛地区滑塌浊积扇砂体的形成和发育与三角洲的规模和建设性、洼陷带的古地形特征及构造活动等因素密切相关。Based on the comprehensive analysis of geological,well logging and seismic data,the characteristics of sedimentation and development of slump turbidite fans in Es_3 in Dongxin region are analyzed.The fans can be divided into three microfacies.The vertical sequence and distribution modes of slump turbidite sands in this area are established.The factors controlling the development of these sands are investigated.It is thought that the development of slump turbidite sands was closely related to the scale and constructivity of delta,the palaeotopography features of the sag,and tectonic movement.
