  • The heat-press simulation experiment is the most direct method for studying the ability of hydrocarbon-generating in source rock.This paper selects by examinations respectively three rock samples in the Member 3 of the Shahejie Formation of Banqiao,Qikou and Beitang Depression to do the heat-press simulation experiments,analyzing with contrasted to the hydrocarbon outcomes,the oil-gas production rate and its phase characteristic.The result shows that three source rocks are all the highly ability of hydrocarbon-generating,the biggest hydrocarbon-generating rate can amount to 300~350kg/t.The source rock in deep of Banqiao Depression mainly produces condensation oil-gas during mature-high mature stage,while the source rock in deep of Qikou and Beitang Depression pruduces oil during mature stage,and produces condensation oil-gas during high mature stage.On the experiment,by changing the experiment pressure to study its influence on hydrocarbon-generating rate and outcome constitution and hydrocarbon-generating phase.In the end,the author clarified that superpressure changes the traditional hydrocarbon-generating mode,enlarging depth and scope of existing oil phase,and extending frontier areas to look for oil.
