摘 要:
基于对准噶尔盆地乌夏断裂带构造特征和构造演化的研究,依据断裂的分割性、构造变形强度、地层展布、基底起伏形态等,将乌夏地区（盆地亚一级构造单元）划分为乌尔禾冲断带、乌尔禾断褶带、乌尔禾单斜带、乌尔禾-夏子街冲断带、乌尔禾-夏子街单斜带、夏子街-红旗坝冲断带、夏子街-红旗坝断褶带和夏子街-红旗坝单斜带等8个次级单元,显示了东西分区、南北分带的特征。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了研究,认为断褶带油气藏类型最发育,是主力产油区,单斜带勘探潜力大,是油气的远景区。[著者文摘]

Abstract:
The Wu-Xia fault belt of Junggar basin is divided into eight second-order tectonic units based on the study on tectonic features and tectonic evolution, such as Wuerhe thrust belt, Wuerhe fault-fold belt, Wuerhe monocline belt, Wuerhe-Xiazijie thrust belt, Wuerhe- Xiazijie monocline belt, Xiazijie-Hongqiba thrust belt, Xiazijie-Hongqiba fault-fold belt and Xiazijie-Hongqiba monocline belt, which reflect the characteristics of structural segmentation in east-west direction and structural zonation in south-north direction. According to the development of structural traps and the conditions of hydrocarbon accumulation, these second-order tectonic units are studied in hydrocarbon accumulation type and distribution. It is concluded that the fault-fold types in this area are most developed and serve as major oil production areas; the monocline belts are of the greatest explorative potentials, being the favorable prospecting areas.[著者文摘]
