| 摘 要： | 综合利用岩心、测井、粒度分析、电镜分析等资料，确定了孤岛油田中二中区28-8井区馆陶组上段第四砂层组为曲流河沉积，研究区内主要发育河道、河道边缘、泛滥平原和废弃河道四种亚相，进一步划分为河道充填、边滩、天然堤、决口扇、河漫滩、河漫洼地、泛滥平原等7种微相。根据砂层划分结果，对该区4个小层的沉积微相进行了研究，掌握了沉积微相的时空展布和变化规律，为储层非均质性研究及油田动态开发提供了可靠的地质依据。

| Abstract: | The fourth sand group in upper member of Guantao formation at 28-8 well area of middle-2district of Gudao oilfield belong to meander river sediment by using core,logging,size analyses and SEM.This district is further divided into 4 sub-facieses of river channel,embankment flood plain and abandoned channel sub-facies,and into 7 micro-facieses of channel filling,sand bar,natural barriers,bursting fan,low-ling land,flood land and abandoned channel micro-facies.On the basis of sands dividing,the sedimentary facieses of 4 sand beds at this district are analyzed.The results can provide a geological foundation for the research of heterogeneity and oilfield development. |
