在取心井单井微相分析的基础上、系统论述了朝阳沟油田扶余油层（ＦⅠ＿３～ＦⅡ＿３）曲流河沉积环境的各种沉积微相特征及其垂向沉积层序模式。利用测井曲线的幅度、形状和顶底接触关系三个要素，建立了适合本区扶余油层曲流河环境的各种沉积微相解释的测井相模式，为（ＦⅠ＿３～ＦⅡ＿３）各小层平面沉积微相和砂体分布研究及储层非均质性研究奠定了基础。
Based on the single well microphase analysis of coring well, the characteristics of sedimentary microfacies and its vertical sedimentary sequence model are systematically discussed in sedimentary environment of Fuyu oil layer (FⅠ_3 ~ FⅡ_3) in Chaoyanggou oilfield. Based on the three factors of the amplitude, shape and top-bottom contact of well logging curve, the logging facies model for the interpretation of sedimentary microfacies suitable for the meandering river environment of Fuyu reservoir in this area is established. Plane sedimentary microfacies and sand body distribution and reservoir heterogeneity laid the foundation.
