摘要

摘要: 科特迪瓦盆地是西非几内亚湾北段一个东西向的具拉分性质的复杂盆地,盆地具有转换大陆边缘与被动大陆边缘叠置的性质.盆地经历了3期构造演化阶段:阿普特期以前为前裂谷期;阿普特期—塞诺曼期早期为裂谷期;塞诺曼期至今为后裂谷期.盆地3期演化相应地建立了不同类型的沉积体系.科特迪瓦盆地已发现的油气聚集区带集中分布在北缘雅克维尔槽地南侧的东西向正向构造带上.油气成藏模式主要是"裂谷层序型成藏模式"和"被动大陆边缘层序型成藏模式".圈闭类型以构造型、构造—不整合型和地层型为主.

Abstract: The CÖte D'Ivoire Basin is an east-west oriented and elongated basin located in the north of the Gulf of Guinea,the West Africa.The basin is characterized by both transcontinental margin and passive continental margin.The tectonic evolution is divided into 3 phases: pre-rift phase before Aptian,rift phase from Aptian to the early Cinemania,and syn-rift phase ever since Cinemania.Different sedimentary systems form during different phases.The discovered hydrocarbon reservoirs mainly locate in the east-west oriented positive structures in the south of the Jacqueville trough.There are 2 accumulation patterns: rift stratigraphic one and passive continental margin stratigraphic one.Traps are of structural,structural-unconformity and stratigraphic types.
