摘要
通过简化有机质成烃机理,利用有机演化过程中元素组成的变化,建立了不同排烃条件下干酪根成烃的数学模型,计算了不同演化程度时的干酪很累计产烃率和有机碳恢复系数。结合实验室模拟结果,分析讨论了排烃条件对有机演化进程的影响。该方法可为油气资源评价提供较为系统准确的参数。
A mathematical model for the generation of hydrocarbon from kerogen is presented by simplifying the complicated process of organic matter maturation and using the change of elemental composition during maturation.The generation of hydrocarbon and the restoration coefficient of organic carbon abundance are calculated with the model.On the basis of the results of modelling and laboratory evaluation of kerogen,the influence of conditions of expelling hydrocarbon on the maturation of organic matter is discussed.Such an influence is shown to be appreciable and must be taken into consideration.This method can also provide a group of systematic and accurate parameters for the evaluation of hydrocarbon resources.
