通过对黄桥地区烃源岩进行封闭热模拟实验，获得了不同成熟度的系列样品，对实验的液态产物进行地球化学特征分析，并将未抽提与抽提的样品进行开放热模拟实验，探讨其二次生烃的动力学特征。随着热模拟温度的提高，烃源岩二次生烃活化能的分布逐渐后移，活化能整体增大。未抽提样品中残留有初次生烃的产物，其二次生烃起始温度低于抽提样品。由于未抽提样品中的残留烃在加热过程中进行了二次裂解，未抽提样品的活化能在36～50kcal/moL之间存在一个独立的小峰，而抽提的样品基本没有。溪1井二叠系大隆组烃源岩的生烃史模拟，表明其二次生烃的潜力较大。

After closed thermal simulation experiments of source rocks in Huangqiao area ,a series of samples with different maturity were obtained ,the geochemical characteristics of liquid products were analyzed .Open thermal simulation experiments were carried out with extracted and no-extracted samples to explore the dynamics characteristics of hydrocarbon regeneration .With the increased temperature of thermal simulation experiments ,the distribution of activation energy of hydrocarbon regeneration gradually moves backward ,and the whole activation energy increase .Because primary products remained in no-extracted samples ,their initial temperatures of hydrocarbon regeneration are below that of the extracted samples .In no-extracted samples residual hydrocarbon cracked again in the heating process ,so they have a small separate peak between 36kcal/moL to 50kcal/moL ,and the extracted samples have not .The simulation of hydrocarbon generation history of Dalong formation in Xi1 well shows that the source rocks have a great potential of hydrocarbon regeneration .
