通过对库车坳陷各测点地温梯度值的统计分析,地温与深度的回归分析,以及对地温影响因素的地质分析,认为该坳陷在浅部和深部各存在1个正常地温系统,在中部则存在1个异常地温系统。同时还认为,中部异常地温系统主要是受逆断层活动的影响所形成;气层地温梯度值偏低,主要是由于天然气在向浅部运移的过程中,体积发生膨胀而降温、吸热所致。库车坳陷正常地温总体水平偏低,则与该坳陷新生界沉积厚度大,受喜马拉雅运动强烈挤压、沟通深部热源的通道条件不发育、第三纪岩浆侵入和喷发活动不活跃等因素有关。
Through the statistical analysis of the geothermal gradient values at each measuring point in the Kuqa Depression, the regression analysis of ground temperature and depth, and the geological analysis of the influencing factors of geothermal temperature, it is concluded that there exists a normal geothermal system in the shallow and deep parts of the depression. In the middle there is an abnormal geothermal system. It is also believed that the anomalous geothermal system in the central area is mainly formed by the thrust fault activity. The low geothermal gradient value of the gas layer is mainly due to the volume expansion and cooling of natural gas during the migration to the shallow part. To The overall normal ground temperature in the Kuqa Depression is lower than that of the Cenozoic in the depression, with thick sediments of the Cenozoic, strong pressure from the Himalayan movement, poor access to deep heat sources, intrusion of the Tertiary magmatism and eruptive activities related.
