古地形地貌是控制一个盆地后期沉积相发育与分布的一个主要因素,同时在一定程度上控制着后期油藏的储盖组合,开展古地貌恢复工作及探讨古地貌对后期油气藏关系对于油田勘探具有重要的指导意义。以饶阳凹陷马西洼槽沙三段为例研究了古地貌对层序中沉积体系发育规律的影响,重点论述了发育较广泛的古凸起带和下切沟谷带随基准面旋回变化而对不同类型沉积体系发育所产生的影响。
The palaeogeomorphology is a major factor controlling the development and distribution of sedimentary facies in the late stage of a basin. At the same time, it controls to some extent the reservoir-cap assemblage of late reservoirs, restores the paleogeomorphology and discusses the relationship between the paleogeomorphology and later reservoirs. It has important guiding significance. This paper studied the influence of Paleogeomorphology on the sedimentary system development in the sequence in the third member of Shahejie Formation in the west part of the Masaiwa depression in the Raoyang Sag. The paleo-uplift and the undergrowth of the broader development were mainly discussed. The impact of different types of sedimentary system development.
