摘　　要：根据岩心资料、测井资料,分析鄂尔多斯吴起油田曾岔区块延长组长6油层组沉积微相。经过地层精细对比与划分得到,吴起油田曾岔区块区长6油层组可分为6个小层。沉积微相研究认为长6油层为三角洲前缘沉积体系,并发育水下分流河道、分流间湾、河口坝三种沉积微相。The sedimentary microfacies in Chang-6 reservoir,Yanchang Formation,Zengcha Block,Wuqi Oilfield were analyzed according to the core and logging data. The reservoir can be divided into layers through the fine stratigraphic division and correlation. The research of sedimentary microfacies shows that Chang-6 reservoir is a delta front sedimentary system,in which three sedimentary microfacies are developed including subaqueous distributary channel,distributary bay and mouth bar.
