沉积盆地的热历史是盆地的热动力学反映,直接影响烃源岩的生排烃时间。本文恢复准噶尔盆地腹部地区典型单井的温度演化历史,为成藏期次的研究奠定了基础。热史模拟结果表明,准噶尔盆地在早二叠世末期经历了一次热流高峰,此后的热流值一直降低至现今的平均值42.3m W/m2。
The thermal history of the sedimentary basin is a thermodynamic reflection of the basin and directly affects the hydrocarbon generation and expulsion time of source rocks. In this paper, the history of temperature evolution in a typical single well in the abdomen of Junggar Basin is recovered, which lays the foundation for the study of the period of hydrocarbon accumulation. The results of the thermal history simulation show that the Junggar Basin experienced a heat flux peak at the end of the Early Permian, and the subsequent heat flow value has been reduced to the present average value of 42.3 mW / m2.
