摘要
基于对准噶尔盆地乌夏断裂带构造变形特征的研究,依据断裂的切割性、构造变形强度、地层展布特征、基底起伏形态等将乌夏断裂带划分为山前冲断带、乌夏断褶带、南部单斜带3个次级构造单元.乌夏断褶带自西向东进一步划分为百乌断褶区、乌尔禾断褶区、乌夏冲断区、夏子街断褶区4个次一级构造单元.依据构造圈闭发育程度、油气运聚条件等,对各次级构造单元的油气成藏类型及分布进行研究,认为断褶带油气藏类型最发育,是主产油区,单斜带勘探潜力大,是油气的远景区.
Based on the study about tectonic transfiguration features ,fault-cutting degree, style of structural deformation, stratigraphic distribution and the relief of basement,The Wuxia fault belt of Junngar basin is divided into three second-order units includeing frontland thrust belt, Wuxia fault-fold belt and south slope.From east to west the Wuxia fault-fold belt is divided into four still more second-order units including Baiwu faulffold district ,Wuerhe faultfold district, wuxia thrust district and Xiazijie faultfold district. All those show the features of the south and north zonation and inter zonal in Wuxia fault zone .On the authority of the distance from source rocks, accumulation condition of hydrocarbon and the development of structure traps,the second-order units were assessed on types and distribution of pool, the result shows that fault-fold belts are the main hydrocarbon area with all sorts of pools, slopes has great hydrocarbon potential in future.
