Abstract:

According to thermo-degradation kinetics data from laboratory and relational formula between activational energy and polymer lifetime established by Toop, the authors calculated the time or temperature of kerogen evolution, and find a new way to get the kinetics data from the laboratory thermo-simulation to apply in geology. The time-temperature relation diagrams and tables of every conversion stage in the kerogen oil-generation phase calculated with the method mentioned above, and the stratum temperature (or time), can be used to calculate the amount and time (or temperature) of oil generation. The result shows that the variation of the reaction speed with different temperature is complicated in different conversion stages of each kerogen oil-generation phase, so it is necessary to make a field survey in different research areas.
