Many researches indicate that the carbon isotopic composition of kerogen in hydrocarbon source rocks is mainly affected by kerogen types, and the composition can be used as an important evaluation index of hydrocarbon source rocks types, sedimentary environment and oil and gas source correlation. This method has been widely applied. Through the research of organic carbon abundance, geochemical characteristics, thermal evolution characteristics and carbon isotopic composition of kerogen in Carboniferous-Permian hydrocarbon source rocks of typical sections in Ejina Banner and its vicinities, it is showed that the Carboniferous-Permian hydrocarbon source rocks in the area are the mud rocks which formed in shallow marine shelf facies, and the source rocks have the characteristics of middle organic carbon, type II kerogen and mature-overmature evolution stage.
