库车坳陷中部上三叠统发育了一套的典型的浊积岩系,既有代表浊流沉积特征的多种底痕构造,又有特征的鲍玛序列,浊流沉积通过坳陷东北部的辫状河三角洲前缘陡坡带进入盆地中心,由于晚三叠世处在稳定的坳陷沉降阶段,加之湖盆底部地形平缓,因而浊积岩系相对较薄,仅发育D相一个浊积岩相,显然这是一种典型的远源浊积岩。与浊积岩共生的深湖相烃源岩和辫状河三角洲相储集层及盖层十分发育,从而证实本区中生界有着良好的油气勘探远景
A typical turbidite series has developed in the Upper Triassic of the central Kuqa Depression. Both turbidite sediments represent the turbidite sedimentary features, and the characteristics of the Bowman sequence and turbidity flow sediment flow through the northeastern depression Due to the stable sedimentary subsidence stage in the late Triassic and the gentle terrain at the bottom of the lake basin, the turbidite system is relatively thin and only D-phase turbidity is developed It is clear that this is a typical far-source turbidite. The deep lacustrine source rocks and braided delta reservoirs and caprocks, which were symbiotic with turbidite, developed very well, which proved that the Mesozoic in this area has good prospect of oil and gas exploration
