Abstract: It isn t very satisfactory to explain the hydrocarbon formation in carbonate rocks with thermal evo-lution of kerogen. In this paper a tentative viewpoint was proposed that there is a kind of potential hy-drocarbon generation matters(salt of fatty acid)in carbonate rocks,for it is of special physical and chemi-cal properties, it is very difficult to obtain the pure salt of fatty acid from sedimentary formation. Thus,we prepared magnesium stearate by chemical synthesis. Magnesium stearte, stearic acid and magnesiumstearate plus CaCO3 were used as simulation samples at 3000℃and 3500℃.The results of the simulationindicated that hydrocarbon conversion ratio of magnesium stearate is higher than that of tearic acid. Thedistribution of reaction products suggested that alpha cleavage is predominant process, in the meantime,βandγ-cracking has also an obvious preponderance. From the experiments of the salt of fatty acid, thenew enlightenment will be gained about hydrocarbon generation in carbonate rocks.
