摘要

总结南屯组地层层序、体系域的识别与划分标志,将目的层自下而上划分为2个三级层序,建立层序地层格架,并根据初次湖泛面和最大湖泛面特征将每个层序进一步划分为低位域、水进域和高位域三个体系域。通过对地震、岩心、钻、测井资料综合分析,识别出乌尔逊凹陷乌北地区南屯组发育扇三角洲相、辫状河三角洲、湖泊相等三种沉积相类型。其中辫状河三角洲发育在湖盆的东缘缓坡带,扇三角洲主要发育在西缘陡坡带。
According to the identification marks of the stratigraphic sequence and the system tracts in Nantun,the target stratum is divided into two third-order sequences,The establishment of sequence-stratigraphic framework,which is divided further into three system tracts including the low-stand systems tract(LST),the transgressive systems tract(TST) and the high-stand systems tract(HST) according to the characteristics of the first surface(FFS) and the maximum surface(MFS).It is recognized that three types of sedimentary facie including the fan delta facie,the braided stream delta,the lake facie and so on are developed in Nantun of Wubei zone in Wuerxun depression by analyzing the data of seismic, rock core,drilling and logging.Braided river delta develops in the basin with the eastern edge of the back slope,while the fan delta develops in the basin with the western edge of the actic region.
