以鄂尔多斯盆地富县地区延长组长1曲流河露头为例,采用传统沉积学和构型要素分析方法,从岩相及岩相组合、构型要素、层次界面等多个方面对研究区露头进行内部构型分析,识别出6种主要的岩相类型,4种构型要素;划分了主要砂体类型的内部组成和界面,在主要砂体的内部识别出4级界面。 Taking the outcrop of Meandering Stream 1 in Yanchang Formation in Fuxian area of ​​Ordos Basin as an example, the authors used traditional sedimentology and configurational element analysis methods to study the outcrops of the study area from various aspects such as lithofacies and lithofacies assemblages, structural elements and hierarchical interfaces Six major lithofacies types and four types of structural elements were identified. The inner composition and interface of the main sand body types were identified, and the four-level interface was identified in the main sand body.
