摘　　要：本文综合考虑了成岩压实、生烃、运移、有机质类型,对现今残余有机碳百分含量的影响,以干酪根中无效碳在生烃过程中,其绝对含量保持恒量这一原则为方程的平衡条件,推导出原始有机碳百分含量恢复系数K_p和原始有机碳总含量恢复系数K_a,为更好地恢复生烃史和计算油气资源量创造了条件。<ABSTRACT>: The influence of diagenetic compaction, hydrocarbon-generation, migration and type of organic matter to the percentage of present residual organic carbon is considered comprehensively in this paper. Taking the absolute content of inefficient carbon in kerogen staying the constant in the process of hydrocarbon generation as equilibrium condition of the equation, the recovery coefficients Kp and Ka for the percentage and total content of original organic carbon are deduced respectively. It provides a chance for restoring the hydrocarbon generation history and calculating oil and gas resources better.
