通过对塔中地区东河砂岩段的岩石类型及其组合、沉积构造、砂岩粒度分布特征及砂体形态的研究,确定了区内东河砂岩段的沉积相类型,微相组成以及主要沉积微相的特征。并在小层划分、对比的基础上分析了小层沉积微相的特点和平面展布特征。
Based on the analysis of the rock types and their assemblages, sedimentary structures, the distribution characteristics of sandstone and the sand body morphology of the Donghe sandstone section in the Tazhong area, the sedimentary facies, microfacies and major sedimentary micro-facies Phase characteristics. Based on the analysis and comparison of small layers, the characteristics of small sedimentary microfacies and plane distribution characteristics are analyzed.
