利用爱沙尼亚奥陶系含藻干酪根未成熟生油岩样品的加水热模拟实验结果，计算了下古生界藻干酪根在各不同演化阶段的平均表观活化能和频率因子。发现其演化的整个过程不完全符合化学反应的一级反应，而是分段符合，动力学参数随演化程度的升高而先降低后增加。其计算结果对于我国下古生界及中上元古界生油层盆地模拟和资源评价具有重要的参考价值。
Based on the hydrothermal simulation results of immature kerogen samples from kerogen kerogen of Ordovician in Estonia, the average apparent activation energy and frequency factor of kerogen kerogen in different evolution stages were calculated. It is found that the whole process of evolution does not completely accord with the first-order reaction of chemical reaction, but it is subdivided. The kinetic parameters decrease and then increase with the increase of the degree of evolution. The calculation results have important reference value for the basin simulation and resource evaluation of Lower Paleozoic and Middle-Upper Proterozoic oil and gas reservoirs in China.
