| 摘 要： | 震旦纪一寒武纪库鲁克塔格、英吉苏地区为陆内裂谷盆地。加里东末期与早海西运动造成塔东地区的普遍抬升剥蚀，孔雀河斜坡、罗布庄凸起开始形成，早二叠世，塔里木板块与中天山地块、哈萨克斯坦一准噶尔板块最终碰撞拼贴，古天山造山带相继形成。燕山晚期，受中特提斯洋关闭影响。塔里木盆地基底随造山带的构造抬升而部分抬升，喜马拉雅期开始，在南北向挤压力作用下，收缩、隆升的山体侧向扩张，向沉积盆地逆冲形成型逆冲推覆构造。造山带和盆地的共同演化不仅形成了多套烃源岩，而且控制了古生界和中新生界两套不同的油气成藏系统。元古界地层由北向南推覆，可能预示着在库鲁克塔格南缘西段山前前寒武纪地层下部保存有古生代和中新生代烃源岩建造，如果配有有利的油气储盖组合和圈闭，有望在山前获得突破。

| Abstract: | The Kuluketage and Yingjisu sags are two rift basins developed on the Sinian-Cambrian, Kongque River slope and Luobuzhuang salient formed in Late Caledonian-pre-Hercynian due to the uplift of East Tarim. The Tarim plate collided with central Tianshan block and Kazakhstan plate in the pre-Permian, leading to the formation of the Tianshan orogenic belt. The basement of the Tarim Basin uplifted along with the orogenic belt in Late Yenshanian. In the Himalayan period, the thrust fault nappe structure was formed because of lateral spreading of the contracted and uplifted orogenic belt. The evolution of the Basin-Range Coupling not only led to the formation of many hydrocarbon-bearing rocks, but also led to the formation of the Palaeozoic and Mesozoic-Cenozoic systems of oil and gas accumulation. For the Proterozoic strata napping from north to south, it is indicated that the Palaeozoic and Mesozoic-Cenozoic hydrocarbon-bearing rocks were preserved in southwestern Kuluketage Mountain. A breakthrough will be made in prospecting oil and gas in piedmont zones if oil and gas reserves and traps do exist. |
