本文用一次反应的化学动力学规律,模拟沉积盆地中有机物质演化形成石油的过程。通过对东营沙三段生油岩测得的大量数据和松辽、黄骅地区的部分数据,用二元统计回归分析方法计算出其表观活化能为7—16千卡/克分子,同时求出频率因子的数量级范围。通过回归检验,求出其相关系数可达0.90,这就验证了沉积盆地有机物质演化形成石油的过程服从于化学动力学规律。文章还对石油组份形成速度和生成时间进行了讨论。
In this paper, the chemical kinetics of a reaction was used to simulate the evolution of organic matter in the sedimentary basin to form petroleum. Based on the large amount of data measured from the source rocks of the third member of Dongying Formation and some data of Songliao and Huanghua areas, the apparent activation energy of the samples was calculated to be 7-16 kcal / mol using binary statistical regression analysis The order of magnitude of the frequency factor. Through the regression test, the correlation coefficient is 0.90, which verifies that the evolution of organic matter in the sedimentary basin obeys the rule of chemical kinetics. The article also discussed the formation of petroleum components and the time of formation.
