通过大量的地层测温资料综合分析确定了吐鲁番 -哈密盆地不同构造单元的现今地温梯度及大地热流值 ,该盆地 (以下简称吐哈盆地 )现今地温梯度为 2 .50℃ /1 0 0 m,大地热流值为 47.8m W/m2 ,现今地温梯度及大地热流值分布具有东高西低的特点。吐哈盆地现今地温梯度及大地热流值高于塔里木盆地及准噶尔盆地 ,现今地温场受地壳厚度、基底结构及盆地构造的控制。吐哈盆地现今地温对烃源岩的油气生成有重要控制作用 ,台北凹陷属持续埋藏增温型凹陷 ,烃源岩现今仍处于成油高峰期。哈密坳陷、托克逊凹陷部分地区烃源岩古地温高于今地温 ,对烃源岩生油过程起控制作用的是古地温而不是现今地温
The current geothermal gradient and the geothermal current value of different tectonic units in the Turpan-Hami basin are determined through comprehensive analysis of a large number of formation temperature data. The present geothermal gradient of this basin (hereinafter referred to as Tuha Basin) is 2.50 ° C / 100 m, The value of geothermal heat flow is 47.8 mW / m2. Nowadays, geothermal gradient and geothermal flow distribution have the characteristics of high east and low west. Nowadays, the geothermal gradient and the geothermal heat value in Turpan-Hami Basin are higher than those in Tarim Basin and Junggar Basin. At present, the geothermal field is controlled by crustal thickness, basement structure and basin structure. The current geothermal temperature in the Turpan-Hami basin plays an important role in controlling hydrocarbon generation in source rocks. The depression in Taipei is a continuous burial temperature-increase depression, and source rock is still in the peak of oil production. The ancient geothermal temperature of the source rocks in the Hami Depression and the Tokchon depression is higher than the current geothermal temperature. The controlling effect on the source rock oil generation process is the paleogeothermal rather than the current geothermal temperature
