Abstract: It is controversial about the origin of the natural gas in Minfeng area. By using thermal simulation experiment of the sealed system, the genetic mechanism of Eocene source rocks and oils are discussed in the generation process of hydrocarbon, the generation kinetics of the gas and some individual hydrocarbon. The result shows that the activation value of oil cracking is 30 kJ/mol higher than the thermolysis of source rocks. At the mature phase, the cracking gas from source rock contains less aromatic hydrocarbons and cycloparaffinic hydrocarbons. In view of above, natural gases in Minfeng area is mainly from Eocene source rocks.
