中文摘要	末端扇是一种形成于干旱环境且广泛分布的特殊类型河流体系,在中国末端扇常被混淆为干旱型浅水三角洲,其储层沉积特征具有沉积微相类型单一、水流卸载量波动大、河道以垂向加积为主、砂岩中泥质含量高、砂岩中碳屑呈层分布、河道冲刷侵蚀弱和片流沉积发育特点,形成末端扇不同区带储层砂体的类型、几何学特征、连通性和建筑结构样式等参数向下游规律性变化.本文以松辽盆地三肇凹陷扶余油层为例,认为末端扇具有补给区-分流区连通性好、分流区优质储层发育和条带状/朵叶状断层-岩性油藏为主的特点,改变了以往对该区浅水三角洲储层连通性差、湖岸线控砂和断续状/透镜状岩性油藏为主的认识.文中概述了自末端扇沉积体系提出以来的国内外研究现状,分析末端扇沉积模型、演化规律和储层建筑结构对油气运移机制和聚集规律的影响,为今后陆相含油气盆地勘探提供指导.
英文摘要	The terminal fan is a special type of river system widely distributed in arid environment. It is often confused with the dry shallow delta in China. The reservoir sedimentation is characterized by single-type sedimentary microfacies, large fluctuation of discharge capacity, high argillaceous content in the sandstone, layered distribution of charcoal in sandstone, where channel is dominated by vertical aggradation with a weak erosion and a sheet flow deposition. Several parameters of the sandstone in different zones of the terminal fan, including the types, geometric characteristics, connectivity and architecture style, are regularly changed to the downstream. In this paper, the Fuyu reservoir in Sanzhao depression of Songliao basin is taken for case analysis. The results show that dominantly controlled by banded/lobed fault-lithology reservoir, the terminal fan from feeder zone to distributary zone has a good connectivity, and high quality reservoirs are developed in the distributary zone. The findings have changed the previous understanding that the shallow water delta in this area has a poorly connected reservoir; the shoreline controls the sand body; and the delta is mainly intermittent/lentoid shaped lithology reservoir. This article reviewed the researches on terminal fan sedimentary system since it was put forward, and analyzed the influence of terminal fan sedimentary model, evolution law and architecture of reservoir on migration mechanism and accumulation regularity of hydrocarbon, which will provide a guidance for future exploration of continental petroliferous basins.
