阿瓦提前陆盆地位于塔里木盆地西北部。在新生代柯坪山脉以北东向的沙井子断裂为主滑面剧烈向南东方向逆冲，在沙井子断裂南东侧沉积了巨厚的新生代地层，且向南东方向急剧减薄，形成典型的不对称挠曲沉积盆地，这种盆地是大陆板块碰撞形成陆相盆地后，再次发育在造山带前缘的前陆盆地，它发育的大地构造位置和时间以及成因与周缘前陆盆地和弧后前陆盆地均不相同，可称之为陆内前陆盆地。阿瓦提前陆盆地具有良好的含油气远景，可进一步划分为三个油气聚集区带：沙井子断裂油气聚集带、阿恰断裂油气聚集带、阿瓦提前缘隆起（乌鲁桥—阿拉尔）构造油气聚集带。其中沙井子断裂带是阿瓦提前陆盆地中含油气远景最好的区带
Awati Prehistoric Basin is located in the northwestern Tarim Basin. In the Cenozoic Keping Mountains northwest of the Shajingzi fault-based slippery surface to the south-east direction of the thrust in the southwestern Shajingzi fault deposition thick thick Cenozoic strata, and sharply to the south-east direction , A typical asymmetric flexure-sedimentary basin is formed, which is a foreland basin re-developed in the front of the orogenic belt after continental plate collision to form a continental basin. Its developmental tectonic position and time as well as its origin and peripheral foreland Basin and arc foreland basin are not the same, can be called inland foreland basin. The Awatii foreland basin has a good petroleum potential and can be further divided into three hydrocarbon accumulation zones: Shajingzi fault hydrocarbon accumulation zone, Aqa fault hydrocarbon accumulation zone, Awati tectonic uplift (Uluqiao-Alar) Construct hydrocarbon accumulation zone. The Shajingzi fault zone is the best oil and gas zone in the Awati tectonic foreland basin
