摘要(Abstract)：

选取尼日尔三角洲盆地某深水区块,通过钻井、地震反射特征及地形特征分析,揭示在陆坡内发育的过路朵叶沉积储层及结构特征,建立过路朵叶发育模式,明确地形特征及沉积物源供给对过路朵叶发育及演化的控制作用.结果表明,工区内过路朵叶具有块状充填的沉积特征,表现沉积时受低地形限制快速充填的特征;储层平面分布范围优于线性水道且具有优良的储集性能,其发育规模和平面分布主要受泥岩上拱形成的微型盆地控制,表现一个多期"充填—溢出"过程,可划分为原始地形、初始充填、后期充填、溢出、水道侵蚀等5个阶段,每个阶段沉积储层特征及平面展布特征都存在差异.此外,重力流流体密度、海平面变化对过路朵叶规模、发育位置也具有较大影响.

关键词(KeyWords)：尼日尔三角洲盆地;深水扇;过路朵叶;沉积特征;发育模式
