摘　　要：为了研究含油气盆地源外斜坡区的油气分布规律,在源外斜坡区油气成藏模式及输导通道构成研究的基础上,通过典型油气藏解剖和油气分布与断砂配置输导通道之间关系实例研究,对源外斜坡区断砂配置输导通道对油气聚集的控制作用进行了研究,结果表明:源外斜坡区断砂配置输导通道对油气聚集的控制作用主要表现为以下3个方面:(1)断砂配置输导通道类型控制着源外斜坡区油气聚集层位,同层断砂配置输导通道油气在同一层位,而跨层断砂配置输导通道油气多层聚集分布;(2)断砂配置输导油气路径分布控制着源外斜坡区油气聚集有利分布区,距断砂配置输导油气路径距离小于油气聚集所需的距断砂配置输导油气路径的最大距离区域应是源外斜坡区油气聚集有利分布区;(3)断砂配置运聚油气耦合部位应是源外斜坡区油气聚集的有利部位,断砂配置圈闭位于断砂配置输导油气路径上或附近,有利于捕获油气聚集成藏,应是源外斜坡区油气聚集的有利部位.In order to study the distribution law of oil and gas in the slope area outside the source of an oil-bearing basin, on the basis of the study on the hydrocarbon accumulation model and the composition of transport channels in the slope area outside the source, by studying the relationship between the anatomy of typical oil and gas reservoirs and the distribution of oil and gas and the distribution of broken sand transport channels, the controlling effect of the distribution of broken sand transport channels on the accumulation of oil and gas was studied, the results show that: the control effect of the sand-break distribution transmission channel on oil and gas accumulation in the slope area outside the source is mainly manifested in the following three aspects:(1)The type of transmission channel with fault and sand body configuration controls the oil and gas accumulation layer in the slope area outside the source, the oil and gas accumulation layer in the transmission channel with broken sand in the same layer is in the same layer, while the oil and gas accumulation layer in the transmission channel with broken sand across layers is in the multi-layer distribution;(2)The distribution of oil and gas transmission paths in the fault sand distribution controls the favorable distribution area for oil and gas accumulation in the off-source slope area, and the distance from the fault sand distribution is less than the maximum distance from the oil and gas accumulation required by the fault sand distribution should be the favorable distribution area for oil and gas accumulation in the off-source slope area;(3)The coupling position of oil-gas accumulation in the off-source slope area should be a favorable position for oil-gas accumulation in the off-source slope area. The sand-fault configuration trap is located on or near the oil-gas transmission path of the sand-fault configuration, which is conducive to oil and gas accumulation and accumulation, and should be a favorable position for oil and gas accumulation in the off
