摘　　要：克拉苏构造带位于库车坳陷北缘,克拉1与克拉2构造是位于克拉苏构造带库姆格列木组膏盐岩下的背斜圈闭,而其钻探结果却完全不同。通过构造地震解释和三维构造编图,认为两者之间存在构造变换作用,形成了构造调节带。构造调节带导致克拉苏背斜复杂化,在克拉1与克拉2构造之间的侧接位置形成传递带,传递带以断裂和褶皱的形式存在,在传递带与克拉2构造之间形成了背斜调节带,该背斜调节带是克拉2构造主要的油气圈闭。Kelasu structural belt is located in the northern margin of Kuqa depression.Kela-1 structure and Kela-2 structure are anticlinal traps,which are under salt layer in Kumugeliemu formation of the Eogene in Kelasu structural belt.However,the drilling results are very different between the two structures.It shows that transition structure zone and structural accommodation zone exist between Kela-1 and Kela-2 structures by structural seismic interpretation and 3D structural models.The structural accommodation zone results in the complication of Kelasu anticline.At the side joint between the two structures forms transfer zone which occurs in forms of fault and fold.And anticlinal accommodation zone exists between the transfer zone and Kela-2 structure,which is the main oil-gas trap in Kela-2 structure.
