摘　　要：通过对王集油田核三段三角洲沉积微相研究,将研究区沉积微相划分为水下分流河道、河口坝、前缘席状砂、河道间湾和前三角洲泥岩五种微相,对每类沉积微相的岩性、粒度、测井曲线、物性等进行了分析,建立了不同沉积微相的测井相识别模式,绘制了沉积微相的平面分布图,总结了沉积微相的平面展布特征,为油田的勘探开发提供地质基础。By doing study on the delta sedimentary microfacies of H-3 Member in Wangji oilfield,it is considered that they can be classified into five categories: subaqueous distributary channel,mouth bar,front sheet sand,interdistributary bay and delta mudstone.Based on the analysis of lithology,granularity,well logging curves and physical properties of every sedimentary microfacies,the well-logging facies pattern recognition of different sedimentary microfiches' is established;the plane distribution map of sedimentary microfacies is drawn;finally the planar distribution characteristics of sedimentary microfacies are summarized,which provide some geological foundations for exploration and development of this oilfield.
