摘要
与深水扇有关的储层将处于油气勘探和生产的最前沿。虽然深水扇沉积作用的研究已经取得了一定的进展,但目前国内外对其地质概念和沉积模式等方面的认识仍存在较大分歧。在国内外研究进展的基础上,结合我国南海北部珠江口盆地白云凹陷珠江深水扇系统的沉积特征,文中详细地描述了深水扇沉积体系中下切水道及其充填序列、水道、天然堤—溢岸及叶状体的沉积特征,具体地阐述了深水扇的层序发育特点及层序界面的识别标志。
The reservoirs related to submarine fans will be in the forefront of the hydrocarbon exploration and production.Although many progresses have been achieved in the research of submarine fan depositon,much divergence still exists in terms of their geological concepts and depositional models at home and abroad.Based on the recent progress,and taken Zhujiang submarine fan system in Baiyun Depression,Pearl River Mouth basin for example,the characteristics of incised valleys and their infilling,channels,levee—overbank and lobes were described,and then characteristics of submarine fan sequence and the identification marks of sequence boundries were illustrated in detail in this paper.
