由于古生代-新生代板块活动,导致非洲不同区域具有不同构造特征,形成和发育了不同类型的沉积盆地,主要可归纳为:古、中生代弯曲盆地,中、新生代大陆边缘断陷盆地,板内裂谷盆地和大陆边缘进积三角洲盆地。不同的古地理环境使得不同类型的盆地具有独特的物质充填和不同的富含油气系统,迄今钻探证实的富油气成藏系统可分为5个含油气系统。通过富油气成藏地质条件的分析、不同勘探程度盆地的地质条件类比以及各探区的潜在油气可采储量分析,对非洲油气勘探区进行了分类与综合评价,同时,结合投资区的环境和中国石油勘探公司的自身状况分析,按长期勘探战略、中期发展策略及短期获利3个层面提出了非洲油气勘探战略选区的建议。

Various types of sedimentary basins with different structure styles in different locations were formed in the Africa, in resulting of the plate movements since Paleozoic to Cenozoic. Those basins can be summarized as following types: Paleozoic and Mesozoic flexure basins, Mesozoic and Cenozoic continental margin rift basins, intra-plate rift basin and continental margin progradational deltaic basins. The differences of paleosedimentary environments resulted in unique basin-filling and petroleum systems.
