As an important geochemical technique for studying oil and gas generation,pyrolysis experiment is more and more widely applied.More than 100 publications about pyrolysis experiment are reveiwed,and the developments and new research fields are mentioned in this paper.New experiment techniques would be developed.More attention would be drawn to catalytic mechanism of minerals,the thermal-fluids effects on hydrocarbon formation,the effect of stress on Ro,distribution of humic acid to oil and gas formation,and the effects of super-critical fluids on oil and gas generation.
