摘要
断裂是塔里木盆地西南坳陷的主要构造活动型式之一.坳陷内主要断裂开始形成于海西晚期或喜马拉雅运动期.不同性质的断裂可存在于同一应力场中,从而导致不同构造单元构造变形特征的差异性.沿断裂走向断裂构造特征存在一定的变化.利用正演模拟方法,分析了主要断裂带的发育演化.经分析研究后认为,断裂是控制油气聚集的重要因素,不同性质的断裂对油气聚集的控制作用存在一定的差异.
Faulting is one kind of tectonic events in the Southwest depression in Tarim basin. The major faulting within the depression began during the late Hercynian or Himalayan periods.The faults with different natures can occur in the same stress field, resulting in the difference in the structural deformation features of different structural units. The structural features of fault along the fault trend vary. The evolution of major fault zones is analysed with the forward modelling method. It is suggested that the fault is an important control on hydrocarbon accumulation, which varies with the nature of the fault.
