摘　　要：南八仙油气田是一个由多种地质因素综合作用下形成的构造-岩性复杂油气藏,结合岩心、测井、地震等资料,对该区地层进行对比与分析,研究表明南八仙地区主要分为8个地层组,南八仙地区E31-N22为一个2个超长期基准面旋回,其顶底为K2、K12两个不整合面,且存在5个长期旋回层序,以上升半旋回为主,通过建立标准层、标准井,将E31-N22划分为5个油组、23个砂层组和210个小层。Nanbaxian oilfield is a Structure-lithology reservoirs which formed by the combined effects of a variety of geological factors,Combined with core,logging,seismic data and so on,then comparison and analysis of the stratigraphic in this area are conducted in the paper.Studies show that it can be divided into 8 strata formation,E31-N22 is a two ultra-long-term base level cycle in Nanbaxian oilfield,with K2(top surface) and K12(bottom surface) in unconformity,there are 5 long-term cyclic sequence,taking the rise hemicycle as the main.Through establishing the standard layer,standard wells,it is divided into five oil groups,23 of sand groups and 210 small layers.
