摘　　要：以岩心、测井及综合录井等资料为基础,对十屋油田SN17,SN18区块营城组和沙河子组的沉积相进行了分析。通过区内取心井单井相分析的同时,研究沉积构造、岩石微相特征,识别沉积微相与测井曲线间的关系,建立微相的测井相模式。研究表明本区为湖泊-扇三角洲沉积体系,主要发育扇三角洲前缘、浅湖等亚相,进一步划分为水下分流河道、河口坝、浅湖砂坝等微相。研究区沉积微相的划分以及沉积相模式图的建立将有助于油田的精细开发。Based on core, logging and comprehensive logging data, the sedimentary facies in Yingcheng formation and Shahezi formation of SN17, SN18 blocks in Shiwu Oil Field were analyzed. At the same time through the single-phase analysis of coring wells, sedimentary structures and rock microfacies characteristics were researched, the relationship between sedimentary microfacies and well log curve were identified, electrofacies model of microfacies were established. Research shows the blocks belong to lake-fan-delta sedimentary systems, fan delta front subfacies and shallow lake subfacies developed, and are further divided into the distributary channel sandbodies , river mouth bars and shallow lake bars and so on. Sedimentary microfacies and the establishment of sedimentary facies model will be useful to the fine development of oil fields.
