秋里塔格构造带位于库车前陆逆冲带前锋 ,区域构造位置介于库车坳陷三叠 侏罗系烃源岩生排烃中心与塔北前缘隆起带之间 ,第三系广泛分布两套膏盐岩层 ,发育多套储盖组合和复杂的构造样式 ,石油地质条件非常优越。本文在分析 3个区带的变形特征基础上 ,探讨了盐上层和盐下层的构造成因 ,认为盐上层的构造成因与盐层的流动性有关 ,西段变形比东段强烈 ;盐下层构造成因东、西差异较大 ,东段与盐层的塑性变形无关 ,西段则受其影响。
The Qiulitage tectonic belt is located in the front of the Kuqa foreland thrust belt. The tectonic zone is located between the Triassic Jurassic hydrocarbon source rock-derived hydrocarbon center and the northern Taichung uplift belt in the Kuqa Depression, and the Tertiary is widely distributed Two gypsum salt rock layers, the development of multiple sets of reservoir cover and complex structural styles, the petroleum geological conditions are very superior. Based on the analysis of the deformation characteristics of the three zones, the paper discussed the structural genesis of the upper salt and lower salt strata. It is concluded that the structural reason of the salt upper is related to the fluidity of the salt layer, and the deformation of the western segment is stronger than that of the eastern segment. East and West are quite different. The eastern segment has nothing to do with the plastic deformation of the salt layer and the western segment is affected by it.
