利用有机质的成烃动力学模型计算有机质生油率和生气率，给出了通过逐步递推来恢复有机质原始生烃潜力和原始有机碳（Ｃ￣ｏ）的方法。在海拉尔盆地呼和湖凹陷海参７井中应用的实际结果表明：对于有机质性质较差的源岩，其残余有机碳的修复幅度一般不大，但对已进入生、排烃高峰阶段的样品，其原始生烃潜力恢复的幅度可达０．５０以上。从而表明了有机质原始生烃潜力和原始有机碳恢复对正确评价烃源岩的重要意义。
Based on the hydrocarbon formation kinetics model of organic matter, the raw oil generation rate and the gas generation rate of organic matter were calculated, and the method of recovering the original hydrocarbon generation potential and the original organic carbon (C ~ o) by the stepwise recursion was given. The practical results of the application in the well Hailin 7 in the Hohhot depression of the Hailar Basin show that the recovery of residual organic carbon is not generally large for source rocks with poor organic matter properties. However, for samples that have entered the peak stage of hydrocarbon generation and expulsion, The potential recovery of the original hydrocarbon generation up to 0.50 or more. This shows that the potential of organic hydrocarbon generation and the recovery of primary organic carbon are of great significance for the correct evaluation of source rocks.
