At the lower velocity of temperature increase,the hydrocarbons can be formed advantageously,the secondary hydrocarbon-generating potential of residual organic matter decreases and the beginning temperature of secondary hydrocarbon generation increases.

• 结果表明,初次生烃时较慢的升温速率有利于烃类的初次生成,而残余有机质的二次生烃潜力明显降低,二次生烃时的启动温度增加;
