摘　　要：塔里木盆地巴楚隆起受多期构造运动影响形成复杂断裂体系。色力布亚断裂具有典型的双重结构,由深层逆冲断裂与浅层逆冲推覆断裂组成。深层逆冲断裂分南、中、北3段,断裂各段特征与断裂活动期次有所不同,控油作用也存在差异。南段早期形成,后期长期处于封闭状态,有利于油气保存;中、北段早期长期处于开启状态,晚期停止活动,有利于晚期油气保存。色力布亚断裂具有油气运移通道和封堵油气散失双重作用,断裂南段是油气成藏有利的构造带。Complex fault system is formed in Baehu Uplift of Tarim Basin clue to the influence of multi-stage tectonics. Selibuya Fault has typical double structures and is composed of deep thrust fault and shallow and nappe thrust fault. The cleep thrust fault is divided into southern, middle and northern sections. The characteristics of each section are different from the active time and the control role on oil and gas is different. The southern section of fault is formed early and is at seal condition in later period for a long time, which is conducive to the oil gas preservation. The middle and northern sections of fault are at opening condition for a long time and stop activity in later period, which is good at the oil gas preservation in later period. Selibuya Fault plays double role for oil and gas migration path and preventing oil and gas from dissipating. The southern section of fault is the best tectonic belt for hydrocarbon accumulation.
