在塔里木板块与准噶尔板块碰撞而形成的天山造山带中,产生了分别平行和垂直于天山的走滑断裂系.平行于天山的走滑断裂对盆地不同构造带的形成及改造具有重要的作用,而垂直于天山的走滑断裂则造成了库车前陆盆地的构造分段现象.走滑断裂可形成一系列与走滑相关圈闭,为油气提供聚集场所.主干走滑断裂分隔性较好,派生走滑断裂的连通性较好,因此库车前陆盆地的油气主要聚集在派生走滑断裂发育的地区,而主干走滑断裂则使油气性质东、西分段,南、北分带.

In Tianshan orogen formed by collision between Tarim plate and Junggar plate shaped strike-slip fault system vertical and parallel to Tianshan orogen. The strike-slip fault system parallel to it is of an important effect on the formation and reformation of different structural zones in Kuqa foreland basin, while that of vertical to it gives rise to the structural segmentation in it. Strike-slip faults can form a series of related traps which provide sites for hydrocarbon accumulation. The arterial strike-slip faults have good sealing ability to stop hydrocarbon migration from one side to the others, while the derived strike-slip ones have good connectivity. Hence, the hydrocarbons in this basin could mainly accumulate in area with derived strike-slip faults; the arterial strike-slip faults allow the hydrocarbons to distribute by east-west segmentation and south-north zoning.
