摘　　要：巴楚隆起在加里东、海西、印支—燕山、喜马拉雅等多期、多种构造应力作用下形成了复杂的叠加构造样式,是塔里木盆地重要的油气勘探地区之一。经过多年的勘探研究表明,其油气聚集与断层分布直接相关。巴楚地区主要的断裂可以划分为三级,一级断裂主要有色力布亚断裂带等,二级断裂主要有康塔库木断裂带等,三级断裂主要有海米东断裂带等。在对断裂进行分级的基础上又对其断裂类型,组合形式进行了总结,得出在横向上背冲式断裂组合是巴楚隆起最主要的断裂组合样式,而在垂向上巴楚地区断裂带多具有明显的双层叠加构造样式,或者主断裂与伴生断裂组合形成的"Y"字形、反"Y"字形构造样式。Bachu uplift is one of the important oil and gas explora- tion regions of Tarim basin, under the action of caledonian, hercyn- ian, indosinian-Yanshan and Himalayan period and a variety of tec- tonic stress, Bachu uplift become a complex tectonic style. After years of exploration and research has shown that the oil and gas gathering and distribution is directly related to the faults. The frac- ture of Bachu area mainly can be divided into three primary frac- tures. The first fracture is Serikbuya fault zone, the secondary frac- ture is Contador Kumu fault zone, the third fracture is Haimidong fault zone. On the basis of fracture classification the paper summa- rize the fracture type, combination, and come to the conclusion and recognize the flush type fracture on lateral combination Bachu uplift is the main fracture combination style, while in vertical Ba- chu fault zone has obvious double superposition tectonic style, or the main fracture combined with associated fracture formation of the ＂Y＂ glyph, the ＂reverse-Y＂ glyph structure style.
