Mixed is very general that comes from the natural gas of different layers or different maturity source-rock in generation, migration, accumulation and evaluation. In this paper, method of quantity calculation of mixed-source natural gas is established based on composition and carbon isotopes of methane and ethane. For example, proportion of the natural gas in Jurassic reservoir comes from Xuyi, Xusan and Xuwu Formation source-rock is calculated of Baimamiao gas field of west in Sichuan basin.
Key words： Mixing of natural gas; Composition; Carbon isotopes; Baimamiao gas field.
