河流沉积是我国陆相含油气盆地进行油气勘探与开发的主力油层。因此,研究河流的各种沉积作用、沉积物特征及其分布规律对寻找油气有着重要的意义。近年来河流沉积学已发展到对沉积砂体内部进行精细研究的阶段,对研究河流相储层的非均质性有重要指导意义。以羊三木油田为例,通过河流相储层研究方法,对羊三木油田馆陶油组开展辫状河储层构型研究。
River sedimentation is the main reservoir for oil and gas exploration and development in continental oil and gas basin. Therefore, it is of great significance to study various sedimentation, sediment characteristics and distribution of rivers in the search for oil and gas. In recent years, river sedimentology has been developed to finely study the interior of sedimentary sand body, which is of great significance for studying the heterogeneity of fluvial reservoirs. Taking the Yangsanmu oilfield as an example, the braided river reservoir configuration was studied in the Guantao Formation of Yangsanmu Oilfield by the method of fluvial facies reservoir.
