摘要
塔里木盆地北缘库车坳陷发育有冲断构造带，逆冲方向自北向南，形成时代为中新世到上新世。根据冲断构造成因和圈闭条件，可划分出６种储油构造：背斜、双重构造、重迭断坡背斜、冲断三角带、下盘断坡带和膏盐岩刺穿构造。由于冲断构造带形成时间与油气生成高峰期相匹配，库车坳陷从南到北的储油构造具有不同特征，其油气分布规律与构造条件有关。
In Kuche depression located in the northern border of the Tarim basin, an overthrust belt is developed, the direction of such an overthrust is oriented from north forward south and was formed in Miocene-plicocene.According to their geneses and trapping conditions, 6 types of oil-bearing structures are classified: Anticline, dual stracture, superimposed faultslope anticline, overthrust delta, lower block fault-slope belt,and salt lime piercement structure. The time of the formation of the overthrust belt matched with time of peak of oil generation and the oil-bearing structures have different characteristics from south to the north,the distribution of oil and gas is related to the stractural conditions.
