摘　　要：为了确定南堡凹陷东一段油气运移输导通道及其在油气成藏中的控制作用,在油藏精细解剖基础上分析了油气分布与源岩之间的空间匹配关系,开展了南堡凹陷东一段油气输导特征的研究。结果表明:南堡凹陷东一段油气运移输导通道主要有2种,一种是油源断裂的垂向输导通道,将沙三段或沙一段——东三段源岩生成的油气运移至东一段。另一种是砂体的侧向输导通道,将侧向分流至东一段的油气侧向运移至油源断裂附近的正向构造上聚集成藏。油气运移输导通道对油成藏与分布有3个主要的控制作用:①油源断裂垂向输导为东一段油气运移成藏提供了油源;②砂地比大于20%的区域是东一段油气聚集的有利区域;③油源断裂附近的正向构造是为东一段油气聚集的有利部位。To study oil ang gas accumulation law of k1d1 in Nanpu depression,using research method of oil and gas reserviors anatomy and matching relation between oil and gas distribution and sourcerocks,oil and gas migration transporting pathways of Ed1 and their controlling to oil and gas accumulation in Nanpu depression were studied.It is considered that there are two oil and gas migration transporting pathways：one is vertical migration transporting pathway of faults connected sourcerock,it made oil and gas from Es3 or Es1 ～ Ed3 sourcerock migrate into Ed1.Other is lateral migration transporting pathways of sandbody,it made oil and gas into Ed1 migrate laterally to positive stractures near faults connected sourcerock and from oil and researviors,controlling of oil and gas migration transporting pathways to oil and gas accumulation and distribution has following three aspacts：①Vertical migration transporting provides oil source for oil and gas in Edl to accumulate ;②the areas where ratio between sandstone and stratum is more than 20％ are favorable areas for oil and gas in Edl to accumulate ;③Positive structures near faults connected sourcerock are favorable places for oil and gas in Ed1 to accumulate.
