Abstract: The vitrinite reflectance (R o) is related to its hydrocarbon generation ratio, therefore, the hydrocarbon yielding could be calculated from its R o value. Meanwhile, having calibrated the reactive kinetic parameters of hydrocarbon generation of vitrinite, we can calculate its hydrocarbon yielding if its paleo heat history is known. On the contrary, if when the hydrocarbon yielding is known, it is possible to deduce the heating history it experienced.Based on this basic principle, the kinetic model of hydrocarbon generation of vitrinite is constructed and calibrated, and the theoretical model of restoring paleo heat history, which can be used in sophisticated geological conditions such as in a region once undergone uplift, erosion or non linear variation of paleo teperature, is set up.Combined with measured R o values of practical samples, the paleo heat history of Haican-7 Well is recovered effectively.
