摘　　要：通过钻井、测井资料分析,建立了台兴油田下第三系阜宁组(Ef3)下亚段测井相与沉积微相的关系,研究了台兴油田的沉积微相类型及主要含油气单元———各砂体沉积微相的平面展布特征。研究表明,Ef3下亚段主要砂体沉积微相类型为水下分流河道、河漫滩、河口砂坝以及席状砂沉积微相。Through analyses of drilling and well logging, the authors set up a relationship of well logging facies and sedimentary microfacies in lower subblock of Funing Formation of Pahogene in Taixing oihrield and study the planar distribution characters of the sedimentary microfacies of Taixing oilfield and the sedimentary facies of various sand bodies in the major oil-gas bearing units. It is concluded that the types of major sandbody sedimentary microfacies in lower subblock of Funing Formation of Pahogene are as follows：underwater distributary channel, river flood land, entry sand bar and sheeted sand sedimentary microfaeies.
