| 摘 要： | 西非被动大陆边缘盐盆地是目前世界油气勘探的重点和热点地区,近年来该区发现的油气与盐构造密切相关.西非被动大陆边缘盐盆地主要集中干安哥拉-喀麦隆段,普遍发育厚层盐层,厚度最大可达1500 m,分布范围平均宽度约300 km.盐盆地的发育具有明显的分段性,横向上可以将盐盆地划分为坡上伸展区和坡下挤压区.伸展区又可以细分为坡...

| Abstract: | Salt basins along the passive continental margin of West Africa are becoming one of the most attractive areas for hydrocarbon exploration.The oil and gas discovered recently are related to salt structures.The salt structures are widespread in Anglo-Cameroon,the thickness of salt is up to 1 500 m and the average width is 300 km.These basins can be divided into two parts in horizontal direction:extensional zone and compressional zone,which extend 100-150 km and 100-200 km respectively.The extensional zone inc... |

| Keywords: | West Africa passive continental margin salt structure extensional zone compressional zone |
