提出了以源岩烃降解率为基础的残余有机碳和残余生烃潜力的恢复方法。研究表明,各类源岩残余有机碳恢复系数与镜质体反射率呈线性函数关系。而残余生烃潜力恢复系数与镜质反射率呈二次函数关系。经塔里木盆地和华北地区寒武系、奥陶系高演化海相碳酸盐岩残余有机碳及残余生烃潜力恢复,结果表明,碳酸盐源岩生烃有机质丰度及生烃潜力下限值与碎屑岩基本相同。
The recovery method of residual organic carbon and residual hydrocarbon generation potential based on the source rock hydrocarbon degradation rate is proposed. The results show that there is a linear function between the recovery coefficient of residual organic carbon and the vitrinite reflectance of all kinds of source rocks. The residual hydrocarbon generation potential recovery factor and vitrinite reflectance showed a quadratic function. Residual organic carbon and residual hydrocarbon generation potential of the Cambrian and Ordovician high-evolution marine carbonate rocks recovered in the Tarim Basin and North China. The results show that the lower limit of organic matter abundance and hydrocarbon generation potential of carbonate source rocks Basically the same as clastic rocks.
