摘要
中非Doba盆地位于中非剪切带西端北侧,是1个具有勘探潜力的含油气裂谷盆地,呈东西走向,面积为3.3×104km2。研究认为盆地内发育的断层、背斜等构造为后期油气运聚提供了积聚场所和有效通道,其主要的烃源岩是下白垩统湖相页岩,储集层为河流-湖相沉积环境下发育的砂体,而盖层则是贯穿盆地的页岩、黏土岩、泥岩。明确该区的石油地质特征具有重要的指导意义,不仅可以为中非Doba盆地区域储层评价研究提供参考,也可以为油气勘探提供良好的借鉴。
The Doba Basin in Central Africa is located in the north of the west end of the Central African shear zone.It is a petroliferous rift basin with exploration potential,with an east-west trend and an area of 3.3×104 km2。The research shows that the faults,anticlines and other structures developed in the basin provide the gathering place and effective channel for the later oil and gas migration and accumulation,the main hydrocarbon source rock is the shale developed in the lower Cretaceous lacustrine facies,the reservoir is the sand body developed in the fluvial-lacustrine sedimentary environment,and the caprock is the shale,clay rock and mudstone penetrating the basin.It is of great guiding significance to define the petroleum geological characteristics in the area,which not only provides reference for the regional reservoir evaluation study of the Doba Basin in Central Africa,but also provides good reference for oil and gas exploration.
