摘要
沙井子断裂为塔里木盆地阿瓦提凹陷北部的控凹边界断裂,呈北东—南西向展布,倾向北西,长约180 km.通过对该断裂带的平面分布和剖面特征、断裂发育演化及其对油气聚集成藏控制作用等的分析,指出沙井子断裂带具有明显的分段特征,可分为西、中、东3段。沙井子断裂带自海西运动早期开始发育,主断裂持续活动至今,控制了阿瓦提凹陷北部地区的构造格架和沉积作用、圈闭形成和油气运移,对油气的聚集成藏起到重要的控制作用。
Shajingzi fault is boundary fault in northern Awati sag in Tarim basin,with trend of NE-SW and length of 180 km.The study of such a large-sized fault belt is now relatively not in-depth.Based on the analysis of the fault belt in plane distribution,profile characteristic,development and evolution,and its controlling effect on hydrocarbon accumulation,it is suggested that Shajingzi fault belt can be divided into western part,middle part and eastern part.It begins development since the early period of Hercynian,and its major fault has been active up to the present,which controls the structural framework,sedimentation,trap formation,oil-gas migration and accumulation of northern Awati sag.
