In this study firstly convert ratios of weight loss of organic matter and carbon are calculated on basis of kinetics parameters of weight loss of organic matter and carbon, then combining pressure models for two kinds of resource rock, porosity of rock and the weight ratio of rock and organic matter, the coefficients of the recovery of the original organic carbon content are calculated in the condition of open-system and closed-system for two kinds of resource rock as follows. Clastic rock model(including coaly mudstone) shows that in the condition of open-system the maximal coefficients of the recovery of the organic carbon content for type Ⅰ and Ⅱ kerogen are 3. 03 and 1.44, respectively. In the condition of closed-system the maximal coefficients of the recovery of the organic carbon content for type Ⅰ and Ⅱ kerogen are 1.30 and 1.13, respectively.
