摘要: 通过观察岩心,结合测井、录井资料,运用沉积学方法,分析研究了西江24-3油田发育的沉积微相类型及其特征;识别出研究区整体上为三角洲平原和三角洲前缘沉积,确定了8种沉积微相类型;在此基础上分析了不同的沉积时期各沉积微相的组合特征和平面分布特征,指出三角洲平原分支河道、三角洲前缘水下分流河道、河口坝、远砂坝、席状砂等砂体为有利储集相带,为本区的勘探开发提供依据。

Abstract: Through the observation of cores and well logging data using sedimentological methods, the types and characteristics of sedimentary microfacies of the Xijiang 24-3 Oil Field have been carefully studied.It reveals that deltaic plain and deltaic front deposits dominate the sequence. 8 types of microfacies are recognized. We grouped the microfacies in accordance with their temporal and spatial distribution. It suggested that the reservoirs of the region mainly consist of the microfacies of distributary channels in the delta plain, and the subaqueous distributary channels, mouth bars, distributary bars and sand sheets in the delta front.They are the favorable targets for further exploration.
