Advance in the pyrolysis experiments and kinetic modeling of oil and gas generation

The past decades have witnessed many simulating experiments carried out on the oil and gas generation and some new insight and advances in the kinetics and pyrolysis achieved.This paper is focused on an overview and consideration and the problems under investigation,based on the combination of these achievements and experiment results.The selection of Open-or closed-system for the pyrolysis simulating experiments depends on the pyrolysis goals and the research objects.At preset,the first order,parallel kinetics model remains an important one for the oil and gas generating process research.The isoconsersional method recommended by ICTAC Kinetics Committee is difficult for certain factors studies,such as overpressure and the kinetics model with overpressure effect needs in the future study.The maximum pressure set is expected according to the geological setting and the maximum temperature of pyrolysis is carefully set up for the pyrolysis including oil cracking.
