有各种数学模型可用于模拟于酪根生成石油的天然过程。其中一种数学模型模拟了由几个独立、平行的一级反应共同作用的石油生成过程。作者利用阿伦尼乌斯方程式,绘制了Tissot和Espitalie(1975)的Ⅱ型干酪根(经历了天然成熟作用和实验室的热解)的反应图,作为利用这种数学模型来研究石油天然成熟过程的一个实例。为了进行比较,文中列出了这些反应的数值计算结果。绘制在log_(10)A—E图上的每个点表示一个反应。这些反应随温度的增加而出现的次序由图上的旋转线表示。研究者可根据图上的极大值作出许多推断,并能迅速观察到由于改变模型的假设条件而产生的许多影响。
There are various mathematical models that can be used to simulate the natural processes that generate oil from kerogen. One of the mathematical models simulates the oil generation process that is composed of several independent, parallel first-order reactions. Using the Arrhenius equation, the authors plotted the type II kerogen of Tissot and Espitalie (1975), which has undergone natural maturation and laboratory pyrolysis, as a way to study the natural maturation of oil using this mathematical model An example of a process. For the sake of comparison, the numerical results of these reactions are listed. Each point plotted on log_ (10) A-E represents a reaction. The order in which these reactions appear with increasing temperature is shown by the rotation lines on the graph. Researchers can make many inferences based on the maxima on the graph and quickly observe the many effects that arise from changing the model’s assumptions.
