煤生烃动力学研究进展

Advances in kinetics of hydrocarbon generation from coal

化学反应动力学是评价煤的生烃过程和生烃特性行之有效的方法。目前,煤生烃动力学模型理论研究和标定得到了不断的深化,煤生烃动力学研究在认识煤源岩成烃规律方面也有长足发展,并在煤源岩评价中初见成效。但是在压力条件下,关于生烃动力学在煤源岩定量和动态评价方面的研究则报道较少。另外,对单体化合物形成动力学的研究还处于探索之中。这些研究将代表煤源岩生烃动力学领域未来发展的重要方向。

Chemical reaction kinetics has been considered as an effective method for assessing the process and characteristics of hydrocarbons generation from coal. At present, theoretic researches on the kinetic model of hydrocarbons generation from coal and its calibration have gradually been deepened. Meanwhile, it has a great progress in understanding the regularity of hydrocarbons generation from coal source rocks, and a preliminary effect on the evaluation of coal source rocks using reaction kinetics. However, reports on the quantified and dynamic assessments for coal source rocks through kinetics of hydrocarbons generation under pressurized conditions are still lack. In addition, researches on the kinetics of individual hydrocarbons generation just are being in exploration. These studies represent the future developing tendency of kinetic field of hydrocarbons generation from coal.
