Abstract: In this paper,the authors sum up systematically the micro-petrological characteristics of hydrocarbon generation by an investigation of the hydrocarbon generation of many typical source rocks in China in combination with results of thermal simulation test.The relationship of fluorescence properties of macerals or mineralbitumous groundmass(including intensity,alteration pattern and spectrum)versus hydrocarbon generation is investigated.The geological implication of this research is discussed.The micro-petrological characteristics of hydrocarbon generation can be used not only to investigate the migration and accumulation of liquid hydrocarbon,but also to study the maturity and hydrocarbon expulsion efficiency of different forms of organic matter in source rock.

摘要： 应用有机岩石学方法,通过对我国数块典型烃源岩成烃作用的详细研究,结合热模拟实验成果,首次系统地论述了烃类生成的显微岩石学特征,研究了显微组分与矿物沥青基质的荧光强度、荧光变化形式及荧光光谱特征与成烃作用的相互关系.在此基础上,探讨了其地质应用价值,指出烃类生成的岩石学特征不仅可用来研究烃类的运移与聚集,而且可用于研究显微组分的差异成熟作用及不同存在形式有机质的差异排烃效率.
