生油岩生油气史的定量评价技术目前还处于探索阶段，其原因在于众多学者在探讨有机质成烃的动力学时，未能将干酪根成油或成气这两种具有明显不同特征的反应动力学过程分开进行讨论。利用等温密闭条件下油裂解成气的实验结果，探讨、建立并标定了油裂解成气的化学动力学模型，为把化学动力学理论真正用于同时预测油、气的生成创造了条件。模型理论计算值与实验观测值良好的一致性初步表明所选择和标定的模型的可行性。
The reason for the quantitative evaluation of the history of oil-bearing rocks is still in the exploratory stage. The reason for this is that many scholars, when discussing the kinetics of hydrocarbon formation from organic matter, failed to convert kerogen into oil or gas, which have obviously different characteristics The process is discussed separately. Based on the experimental results of oil cracked into gas under isothermal closed conditions, the chemical kinetic model of oil cracked into gas was established and calibrated to create the conditions for the real application of chemical kinetic theory in the simultaneous prediction of oil and gas generation. Good agreement between model theoretical calculations and experimental observations shows the feasibility of the selected and calibrated models.
