Low mature mudstone from Jiyang depression and Changwei depression have been studied by the thermal simulating experiment. The results show that yield of gaseous hydrocarbon become more and more with increasing simulation temperature and begin increasing rapidly at 350℃. With the simulation thermal heightened, the contents of methane and heavy hydrocarbon are augment and (C2-C5)/(C1- C5) is reducing. Stable carbon isotope analyses display that methane carbon isotope has depressed(350℃ ) and building up exceed 350C. Gaseous carbon isotopic distribution at -24.6‰-42.6‰. The result show that the source rocks can produce oil and gas if they are mature.
