本文以济阳坳陷埕东油田北坡馆陶组河流相砂岩为例，详细阐述了河流相砂体的沉积微相研究方法，将研究区的河流相砂体划分为曲流河、网状河和辫状河三种沉积相，并进一步划分为七类主要的沉积微相。通过单井剖面和井间剖面对比分析，研究沉积微相在垂向上和平面上的变化规律，在此基础上结合地震资料的精细解释，编制了研究区内不同砂层组沉积时期沉积微相平面展布图。
Taking the sedimentary facies sandstone of Guantao Formation in the northern slope of Jiudian Oilfield in the Jiyang Depression as an example, this paper elaborates the research methods of sedimentary microfacies of the facies sand bodies in the river. The sedimentary microfacies of the fluvial sand bodies in the study area are divided into meandering rivers, River and braided river three sedimentary facies, and further divided into seven major sedimentary microfacies. Through the comparison and analysis of single-well section and cross-section, the vertical and horizontal variation of sedimentary microfacies are studied. Based on the detailed interpretation of seismic data, the sedimentary microfacies of different sandstones in the study area Flat layout map.
