【摘要】 本文采用埋藏较浅的未成熟的东濮生油岩样,在岩石评价仪上进行不同升温速率的热解模拟实验,用Friedman方法处理,求得一系列在不同生烃率时不同的动力学参数。将此样品热解生烃动力学模型与该地区沉积速率、地温梯度等地质参数结合,用龙格-库塔法计算出在天然地质条件下,不同埋深处生油岩的生烃率及已生成油气量的数值解。更多还原

【Abstract】 Rock-Evaluation apparatus is used to investigate the pyrolysis kinetics of source rocks from the shallow burial. The different kinetic parameters of the samples for various hydrocarbon evolution values are calculated by Friedman method. Numerical solution of hydrocarbon formation of source rocks in different burial depths under natural geological conditions are obtained with Runge-Kutta method on the basis of the kinetic model and geological parameters.更多还原
