利用一个建立在化学动力学理论基础之上的数学模型来模拟干酪根的自然热降解过程,这是有机地球化学和油气资源量预测技术的一项重要进展。利用数学模拟方法,人们根据少量基础资料(干酪根类型、温度史等)就能够定量地估计干酪根在各个地史时期的演化水平,从而有可能相当准确地回答其他研究方法(样品分析、人工热降解实验等)难于回答的某些重要问题。例如圈闭形成过程与油气生成过程是否配合良好,某些目前尚未钻探的地区或层位有无钻探价值,如此等等。因此,数学模拟是一种既经济又
The use of a mathematical model based on chemical kinetic theory to simulate the natural thermal degradation of kerogen is an important advance in organic geochemistry and hydrocarbon resource prediction. Using mathematical modeling, one can quantitatively estimate the evolution of the kerogen in various geo-historical periods based on a small amount of basic data (kerogen type, temperature history, etc.) and thus be able to respond fairly accurately to other research methods (sample analysis, manual Thermal degradation experiments, etc.) difficult to answer some of the important issues. For example, the trap formation process is well matched with the hydrocarbon generation process, the drilling value is not found in some areas or layers that are not currently drilled, and so on. Therefore, mathematical simulation is both economical and economical
