Numerical simulation of dynamic distribution and accumulation mechanism of deep basin gas

The formation conditions and distribution principles of deep-basin gas reservoir are different from those of the typical hydrocarbon habitat.The formation and conservation of the gas reservoir must meet the force and substance balance conditions.A numerical simulation method for the system of three-dimensional basin was developed in order to derive the data of geology history from the present data.The numerical result is more exact for optimizing the parameters of the initial porosity and compress coefficients.The mathematical model and algorithm were applied to the research of dynamic distribution and prediction of accumulation quantity of deep basin gas.The numerical results fit well with the practice of Turpan-Hami Basin.
