摘要
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.
