准噶尔盆地西北缘前陆冲断带可以划分为西南部的红车断裂带,中部的克百断裂带和东北部的乌夏断裂带,在相邻断裂带之间发育两个具有调节断裂带间位移和应变传递作用的变换带。变换带对研究区中生界沉积的控制体现在:与断裂带主体比较而言,变换带部位发育的沉积类型更加丰富;砂岩粒度较粗,单层厚度较大,横向上分布稳定,推进距离远,砂体往往沿着传递斜坡、变换断层走向富集,可以形成规模巨大的优质储集层。
The foreland thrust belt in the northwestern margin of Junggar Basin can be divided into the Hongche fault zone in the southwest, the Kehui fault zone in the central part and the Wuxia fault zone in the northeast, with two zones between the adjacent fault zones Shift and strain transfer function of the transformation zone. The control of the Mesozoic sediments in the study area by the transformation zone is as follows: compared with the main body of the fault zone, the sedimentary types of the transformation zone are more abundant; the sandstone is coarse, the thickness of the single layer is large, the horizontal distribution is stable, and the propulsion distance Far, sand bodies often pass along the slope, transform the fault to the enrichment, the formation of large-scale high-quality reservoirs.
