摘　　要：针对苏北盆地溱潼凹陷台兴油田阜三段油藏储层非均质严重,高含水开发期水驱动用程度低的特点,综合应用岩心、测井及相关测试资料,对其储层沉积微相及展布特征进行了系统研究。结果表明:该区阜三段(Ef3)为一套辫状三角洲沉积体系,主要发育水下分流河道、河口坝、远砂坝(席状砂)3个微相,其中水下分流河道和河口坝砂体为储集层骨架砂体。分析了研究区主要含油小层沉积微相的时空展布特征,讨论了不同沉积微相剩余油分布特点及挖潜对策,为该油田调整方案制定及动态分析提供了可靠的地质依据。As the aeolotropism of the Fu 3 member reservoir of Taixing Oilfield in Qintong Depression in Subei Basin and the low driving force during high water cut stage in that area, the distribution of microfacies of the reservoir systemically using the datum of cores, log data which is interrelated are studied. It indicates Fu 3 member in that area（Ef^3） belongs to a braided river delta system and develops three microfacies which are subaqueous distributory channel, debouch bar and distal bar. The subaqueous channel and debouch bar are the main sand body. Features of distributing of the microfacies of the main petroliferous bed are analyzed and the features of distributing of the remaining oil and the ways to tap the latent power are discussed.
