  • The relationship between the vitrinite reflectance of residual matter and hydrocarbon yield rate was established through pyrolysis experiments that simulated maturation of organic matter. Ro values calculated through pyrolysis simulation indicative of different maturities were compared to natural evolution profiles. Using these data, an Easy%Ro model and the relationship between H/C ratio and Ro of kerogen were applied based on the multi-stage evolution of vitrinite reflectance. We put forward an Easy%Ro correction chart, a multi-stage H/C correction approach and the formula for the pyrolysis simulation experiment. The hydrocarbon generation model rebuilt using the corrected vitrinite reflectance was much closer to the natural evolution model.
