摘要
基于对准噶尔盆地沉积、含油气系统、勘探目的层及构造演化等地质条件的分析,从控盆主断裂形态、主断裂复合结构、成因机制上探讨了盆地西北缘、东北缘和南缘3条边界断裂的结构类型,分析了压扭性叠合盆地复合边界结构体系及特征。不同期次、不同构造应力方向、不同时间的挤压叠加样式不同,造成盆地主要复合边界结构的差异。地震-地质相结合,对准噶尔盆地控边断裂的3种主要复合边界结构进行了综合解释,划分为4层或3层复合边界结构,解释为4段式或3段式复合边界结构类型。
Based on the sedimentation,petroleum system,explorative target zone and structural evolution in Junggar basin,integrated with the basin-controlling major faulting shape,composite structure and genetic mechanism,this paper discussed structural types of three boundary faults of the northwestern margin,northeastern margin and southern margin of Junggar basin and analyzed the composite boundary structure system and characteristics in the compresso-shear overlay basin.By using the differences of the basinal major composite boundary structure resulted from the compressional and overlay shapes of different episodes,different structural stress directions and different times as well as combination of seismic profile with geologic facies,this paper also interpreted comprehensively the three composite boundary structures of boundary-controlled faults in Junggar basin,classifying as four or three zones of the structures and four or three sections of the types.
