| Abstract: | Determining the genetic type of natural gas is the foundation to systemically studying natural gas geology. The compositions of the natural gas, carbon isotope and lighter hydrocarbon from Yancheng Sag are analysed by the several methods such as relative map method, graphic method and clustering method. It is conclused that the natural gas in Yancheng Sag belongs to the mixed gas of coal type gas and oil type gas, and the oil type gas from sapropelic type kerogen is dominant. |
