世界被动陆缘深水含油气盆地的演化可划分为裂前期、裂谷期以及裂后期(被动陆缘期),裂后期又可划分出热沉降期和漂移期两个亚期.裂谷期发育的裂谷层序和漂移期发育的漂移层序是构成生储盖组合的主要层序.统计发现,盆地的生储盖组合主要有裂谷期生储盖、裂谷期生或混生-漂移期储盖和漂移期生储盖三种组合.三种生储盖组合类型均主要发育海陆过渡相烃源岩、深海相浊积砂岩储层以及海相泥页岩盖层.不同生储盖类型均有较大油气储量.裂谷期生储盖组合的勘探程度较低,潜力巨大；裂谷期生或混生-漂移期储盖组合的储量贡献较大,仍有较大潜力；漂移期生储盖组合的勘探程度高,储量贡献大,是现阶段深水油气勘探的热点目标.

The tectonic evolution of mondial passive epicontinental basins can be divided into three major developmental phases, the pre-rifting, the rifting and the post-rifting phases. The post-rifting phase can be subdivided into thermal subsiding and drifting subphases. Both the rift sequence developed during rifting and the drift sequence developed during drifting can be the dominant strata that comprise source-reservoir-caprock (SRC) assemblages. By statistics, it is revealed that the SRC assembleges in basins can include: Ⅰ. the rifting SRC assembleges， Ⅱ. the compound rifting S and/or drifting RC assembleges, andⅢ. the drifting SRC assembleges. All types of the assembleges mainly consist of the marine/continental transitional source rocks, deepwater turbidite sandstone reservoirs and marine mudstone caprocks. Every assemblage can providea great huge amount of oil and gas reserves. The rifting SRC assembleges are in low extent of exploration and will have huge hydrocarbon potential. The compound rifting S and/or drifting RC assembleges possess of huge reserves and will have great hydrocarbon potential. The drifting SRC assembleges are in high extent of exploration and possess of huge reserves so they are the focus of deepwater oil and gas exploration and production at present.
