通过加水热模拟实验分析了升温速率对有机质演化的影响。从分析结果可以看出,升温速率对残余固体有机质和气、液态生成物均有明显影响,表现在:在较低的升温速率条件下,有机质生烃可以充分进行,而随升温速率增大,气、液态产物的产率降低;残余固体有机质的特征也发生明显的变化,主要表现为残余生烃潜力随升温速率增大而增大。

In this paper, the authors analyze the influence of temperature increase velocity to the hydrocarbon formation of source rock by hydropyrolysis. The research results indicate the obvious affection of temperature increase velocity to solid remains,gaseous and liquid products. At lower temperature,it's sufficient of hydrocarbon formation, the yield of gaseous and liquid products decreases with temperature-increasing velocity rising. In the course of temperature enhancing, there is distinct variation of solid remains, its residual hydrocarbon-generating potential increases with temperature ascending.
