摘　　要：根据岩心微相、砂体剖面层序和砂体平面展布分析,对金湖凹陷阜三段沉积微相进行了研究,研究表明整个凹陷共发育了3个三角洲垛体,其中源于张八岭隆起和建湖隆起的水系在西斜坡形成了广布型的三角洲前缘沉积,另2个位于卞闵杨地区和在宝应地区,三角洲前缘相带分异比较明显,由三角洲前缘的水下分流河道-河口砂坝变为前缘席状砂和前三角洲。水下分流河道和河口砂坝砂体相互连接,形成厚度较稳定的三角洲前缘复合体,加之临近生油层,三角洲前缘砂体具有较大的勘探潜力。Sedimentary microfacies of the 3^ra member of the Funing formation in the Jinhu Depression are interpreted jointly with careful core description, sequence and distribution of sandstone. There are three deltas in the Jinhu depression. A delta front is wide in the Bianminyang area. It originated from the Zhangjialing and Jianhu uplifts. The others are in the Bianminyang and Baoying areas. The main sedimentary microfacies include distributary channel, distributary mouth bar, front sand sheet and interdistributary deposits. The relatively stable distributary sands spread out along the prograding delta front and constitute the dominated petroleum reservoirs.
