摘　　要：以岩心相分析为基础,综合储层岩性、沉积构造及粒度等方面特征,确定了新庄油田Eh_3Ⅰ-Ⅲ储层为扇三角洲沉积体系。其主要发育扇三角洲前缘亚相,微相包括水下分流河道、河口坝、边缘砂和席状砂4类;建立了扇三角洲三维空间相模式,对沉积相平面展布规律进行了分析;探讨了沉积相对储层物性及含油性的控制作用,为储层的综合评价及有利储集相带预测奠定了地质基础。Based on core facies analysis and in combination with lithology, sedimentary structures and rock grain size, it is believed that Reservoir Eha I - III in Xinzhuang Oilfield deposited in a fan - delta sedimentary system. Fan - delta front sub - facies is predominant and microfacies include underwater distributary channel, mouth bar, marginal sandbody and sand sheet A three - dimensional facies mode of fan- delta is built; the lateral distribution pattern of sedimentary facies is analyzed; and the control of sedimentary facies on reservoir physical properties and oil -bearing properties is discussed. These studies lay a geological foundation for comprehensive evaluation of reservoirs and prediction of favorable reservoir facies belts.
