摘　　要：M盆地是非洲较大的含油气盆地之一 ,盆地面积 11.2× 10 4km2 ,沉积了白垩系及以上地层 ,最大沉积岩厚度大于 10km。为搞清构造特征及演化史 ,充分利用地震资料 ,应用帕拉代姆的Geosec平衡剖面技术 ,对主要骨干地震解释剖面进行平衡剖面制作 ,计算地层伸缩量 ,帮助对构造变形机制的理解 ,验证解释成果。在构造落实的基础上 ,利用含油气理论 ,分析成藏的主要控制因素 ,找出了油气运聚的主要时期及配套关系 。With an area of 11.2×10 4 km 2 , M Basin is one of the biggest oil & gas basins in Africa. The basin deposits Cretaceous sedimentary rocks and the newer with maximum deposition thickness over 10 km. In order to investigate the structural features and evolution history of the basin, we use seismic data and Geosec technique to make balanced sections of the main seismic lines and calculate the amount of extension and contraction of the formations. The results are used to infer structural deformation mechanism and verify interpretation results. On the base of reliable structure interpretation, the paper analyzes the main control factors of reservoirs, the main times, and relevant relations of hydrocarbon migration and accumulation. All these help us to deploy well locations.
