Abstract: This paper introduces systematically the lab work for the determination of the diffusion coefficient of light hydrocarbon as well as the results obtained.Mathematic models describing the diffusion of light hydrocar boas from source rocks and that for natural gas in gas-pools through caprock have been established to study quantitatively the effect of diffusion on gas accumulation.The dynamic equilibrium principle in the migration and accumulation of gas is put forward with a hope to help the advance of gas exploration in our country.
