EXPERIMENTS ON PETROLEUM GENERATION-CONSIDERATIONS AND OUTLOOK

The study of petroleum generation,based on pyrolysis experiments and by means of reaction kinetics,is a systematical method combined closely with geologic conditions.Based on the summarization of present works on pyrolysis and kinetics,the outlook and prospects were discussed in this paper,and some conclusions and aspects worthy to further studies were proposed:1) up to date,hydrous pyrolysis was one of the best technique for simulating oil formation,and the confined system pyrolysis was still an excellent experiment technique of oil and gas generation/cracking and can be used to carry out hydrous pyrolysis experiments;2) the pyrolysis equipment with the episodic expulsion of hydrocarbon remained to be deve-loped;3) it was sure that pressure affected organic matter maturation,hydrocarbon generation and oil cracking,but the effects were possibly different;4) the kinetic study based on the pyrolysis experiments at single heating rate would not be accepted in the future;5) the kinetic models with the effects of pressure,including hydrocarbon generation and stable isotopic modelling,were expected in further studies;6) most geologic catalysts,except water-soluble,had few influences on oil and gas formation,but they possibly affected petroleum cracking in reservoirs;7) natural gas components and isotopic composition were closely related to accumulation history,to which much attention was expected to pay;8) the study of inorganic matter and its hydrous pyrolysis and the kinetics of non-hydrocarbon gas generation and isotopic evolution were of potential values for scientific research.
