摘　　要：为了研究自然界中地层水对烃源岩成熟过程的物理—化学影响,学者们开展不同条件下的热模拟实验,通过观察分析烃类产物的产率、水介质和烃类产物的氢稳定同位素变化,证明了水介质对烃类产物生成存在不同程度的影响。由于沉积盆地环境中烃源岩热演化是相对低温而漫长的过程(普遍低于200℃),而实验室条件不能完全重现这一地质过程。因此,本文通过总结与对比不同热模拟条件下结论的异同,特别针对自然沉积盆地与室内实验的反应条件的异同性,深入探讨室内实验数据结论的指示意义和局限性,更加全面的认识水介质对烃源岩生烃反应的作用机理及影响程度。In order to study the physical and chemical influence of formation water on the maturation processes of hydrocarbon source rocks in nature,researchers have used hydrous pyrolysis experiments under different conditions,analyzing the yield of hydrocarbon products,aqueous medium and stable isotope changes of hydrocarbon products.They have proved that the aqueous medium had different degrees of influence on the formation of hydrocarbon products.This paper summarizes and compares the previous simulation experiments results.As the thermal evolution of hydrocarbon source rocks in a sedimentary basin environment is a relatively low temperature and long process(generally lower than 200℃),laboratory conditions cannot completely reproduce this geological process.Therefore,this article emphasizes the causes behind the similarities and differences of conclusions drawn under different thermal simulation conditions,especially comparing results from natural sedimentary basins and laboratory experiments,and discusses the significance and limitations of conclusions drawn from laboratory experiment data,so as to better understand the influence of the aqueous medium on hydrocarbon generation in hydrocarbon source rocks.
