| 摘 要： | 通过地震非地震联合解释及多年的勘探研究,认为受基底结构、构造演化、逆冲及走滑断裂等影响,库车-喀什北缘山前冲断带具有东西分段、南北分带的构造特征。自西向东分为喀什北缘、柯坪断隆和库车坳陷三大段,受近南北向逆冲挤压作用,每段均发育多排北东-南西向展布的逆冲褶皱带,其中库车坳陷主要由克拉苏、依奇克里克、秋里塔格构造带及乌什、拜城、阳霞凹陷等呈斜列式展布的次级构造单元组成。普遍发育的膏盐岩塑性层在一系列逆冲和走滑断裂的作用下,使得山前带构造样式更为复杂,发育断层转折褶皱、断层传播褶皱、滑脱褶皱和盐底辟(刺穿)构造等四种基本构造样式及多种组合样式。

| Abstract: | Integrated with the seismic and non-seismic associated interpretation together with the previous study data on oil and gas exploration in the last two decades,we conclude that Kuqa to Kashi Foreland thrust belt have the characteristic features of segmentation from West to East and zonation from South to North.It is controlled by the basement structure,tectonic evolution,thrust and strike-slip faults and so on.It is divided into the northern Kashi fold belt,Keping Uplift and Kuqa depression from west to east... |
