摘　　要：五3东区上乌尔禾组油藏位于准噶尔盆地西北缘克—乌断裂带下盘,整体为一向东南倾的单斜油藏。该区上乌尔禾组顶底均为不整合面,发育一套冲积扇型沉积体系。由于沉积微相、剥蚀程度及断裂发育情况的不同,导致该区上乌尔禾组油藏类型差异较大。在综合研究五3东区地层、构造、沉积特征的基础上,初步认为该区上乌尔禾组油藏类型包括地层—岩性复合油气藏、构造—岩性复合油气藏、地层—构造—岩性复合油气藏、岩性油气藏等。Upper Wuerhe Formation reservoir,ineast of 53 distict is located in the footwallof Ke-Wufault beltin northwestedge ofJunggar basin,is a monoclinic reservoir with southeast dip direction.There are unconformity surfaces both in the top andbottomofUpper Wuerhe Formationin this region,develops a set of alluvial fan sedimentary system.As a result of the differentsedimentary microfacies,denudation degree and the fracture development situation,the reservoir typesin Upper Wuerhe Formationare different.On the basis of comprehensive study,including stratigraphic,structure,sedimentary characteristicsof East of53 distict,weconsidered the reservoir types of Upper Wuerhe Formationwere stratigraphic-lithologic composite reservoirs,structural-lithologiccomposite reservoirs,formation- structure-lithology composite reservoirs and lithologic reservoirs,etc.
