  • Lot of research work has shown that great risk will be introduced by a direct use of thermal simulation of petroleum generation pattern of a source rock. Kinetics method of hydrocarbon generation can be used to exptrapolation of the kinetics of oil and gas formation from laboratory experiments to sedimentary basins. Thus, the data obtained by this method are greater valuable for source rock evaluation. In this paper, the petroleum generation pattern of kerogen of the Lower Tertiary brown black shale from the Dong-ying Depression was studied using a golden tube-high pressure stove, and the petroleum generation kine-tics parameters of the kerogen for the four group compositions of C1,C1-5,C6-12 and C13+ were deduced by a patented software Kinetics. A comparison was made between this result and the geological data, showing that petroleum generation model obtained by this method can match with petroleum generation pattern of the source rocks in geological conditions. The kinetics method of petroleum generation will have wide application in source rock evaluation.
