摘　　要：水下扇沉积在辽河盆地沙三段广泛发育,沉积速度快、横向变化大,储层预测是难点。为准确预测该类储层分布,以储层岩性、电性、厚度、平面变化等信息为基础,运用水下扇沉积理论,通过建立沉积微相模式,深入研究了诸多区块水下扇沉积模式成因机制和微相特点,总结出辽河盆地水下扇沉积主要有近岸型、扇前扇组合型、伸展型、远岸型及滑塌型,有效预测了储层分布,在油田滚动勘探开发中获得了良好效果。Submarine fan had developed extensively in the Es3 of Liaohe Basin.It characterizes rapid deposition and drastic lateral variations;therefore reservoir prediction is a difficult job.Based on data of reservoir lithology,electric property,thickness and lateral variation,a model of sedimentary microfacies has been built to study the formation mechanism and characteristics of submarine fan depositions,and has concluded that the submarine fan depositions in Liaohe Basin mainly include nearshore,composite fan-front fan,extension,distal shore and slide types,thereby effectively predicted the distribution of reservoirs,and achieved good result in progressive exploration and development in the oil fields.
