陆架边缘迁移轨迹与陆坡形态的耦合关系及其深水油气勘探意义:以东非大陆边缘为例

Coupling Relationship between Shelf-Edge Trajectories and Slope Morphology and Its Implications for Deep-Water Oil and Gas Exploration: A Case Study from the Passive Continental Margin, East Africa

陆架边缘迁移轨迹与陆坡地貌形态均对深水沉积具有指示意义,但二者研究相对独立,综合陆架边缘迁移轨迹与陆地地貌形态研究可提升对深水沉积体系和有利储层预测方法的认知.文章基于水深数据和地震资料,精细划分东非被动大陆边缘陆坡类型为下凹型、"S"型和平直型,并定量分析其源汇系统,认为陆坡形态发育主要受区域构造、全球海平面变化和沉积物供给、海底峡谷的共同制约.
