生烃动力学、同位素动力学方法在烃源岩研究中的应用

生烃动力学、同位素动力学常用于烃源岩评价、油气源对比研究中。生烃动力学参数结合盆地热史，可恢复烃源岩在任一时代的生烃史，对构造复杂盆地的二次生烃研究具有独特的优势。利用生烃动力学方法可以实现有机质总量的恢复，在此基础上对高-过成熟样品原始有机质丰度是否有必要恢复进行了讨论；而基于生烃动力学的油气源对比综合考虑热史、成藏期次、成藏过程等各种地质参数对烃源岩生烃的影响，是一种动态的研究方法。

Application of hydrocarbon generation kinetics and isotopic distillation kinetics to the study of hydrocarbon source rocks

Hydrocarbon generation kinetics and isotopic kinetics have been normally used in the evaluation of source rocks and correlation of oil, gas and their supposed source rocks, The hydrocarbon generation history of source rocks at any time may be reconstructed by using hydrocarbon generation kinetic parameters, combined the basin thermal history. So hydrocarbon generation kinetics has its unique advantage for the study of secondary hydrocarbon generation in complicated basins. Recovery of the total content of original organic matter may be realized by the method of hydrocarbon generation kinetics, and on that basis, the necessity of recovery of the original organic matter abundance of highly mature and overmature samples is discussed. Correlation of petroleum source rocks based on hydrocarbon generation kinetics and consideration of the influences of various geological parameters such as the thermal history and stages and process of formation of petroleum accumulations are a dynamic research method.
