摘　　要：东南亚苏门答腊弧后盆地带包括北、中、南三个盆地,这些盆地形成于新生代,经历了同生裂谷、后裂谷以及构造反转三个阶段。根据裂谷作用阶段和相应的储层特征划分出上部、中部、下部和深部共四套油气成藏组合。深部与下部成藏组合主要发育同生裂谷期湖相、海陆过渡相砂岩,中部与上部成藏组合主要发育后裂谷期海相碳酸盐岩、海陆过渡相砂岩。中部油气成藏组合最具勘探价值。Cenozoic Sumatra back-arc basins include Sumatra North, Sumatra Central and Sumatra South ones in Sumatra Island, Indonesia. These basins have undergone the evolution stages from Eocene-Oligocene syn-rifting through Oligocene-Middle Miocene post-rifting to Middle Miocene-Pliocene tectonic inversion. According to rifting and reservoir characteristics, four different plays, i.e. the upper, the middle, the lower and the deeper ones, can be rec-ognized. The deeper and lower plays are characteristic of syn-rifting terrestrial sandstone reservoirs and transitional sandstone reservoirs while the middle and upper plays are characteristic of post-rifting marine carbonate reservoirs and transitional facies sandstone reservoirs. It is indicated that the middle play is of the most significant potential among these plays.
