摘要
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。
According to the hydrous pyrolysis results of immature source rock from Ordovician system,average apparent activation energies and frequency factors of kerosene from the Lower Paleozoic at different evaluation stages are calculated.It indicates that the whole evolution coures is not in accord with the first order reaction,but different evolution stags are in accord with the first order reaction.These calculation results have important reference value to basin simulation and resource evaluation of source rock from the Lower Palaeozoic and Middle nd Upper Proterozozic.
