摘　　要：文中利用一种新的气源岩定量评价方法对南华北盆地上古生界煤的二次生烃机理进行了研究。主要采用两个系列的热模拟实验,即连续生烃热模拟和分段生烃热模拟(模拟沉降—抬升—沉降过程),还探讨了煤岩二次生烃的特点。In this paper, the secondary hydrocarbon generation mechanism of the Upper Paleozoic coal in the South Huabei Basin was studied using a new kind of quantitative evaluation method for gas source rock. Two series of thermal simulation experiments were conducted, that is, the successive hydrocarbon generation thermal simulation and the stepwise hydrocarbon generation thermal simulation (simulating the process of subsidence uplifting subsidence). Besides, the characteristics of secondary hydrocarbon generation for coal rock were also discussed.
