Summary: | The invention discloses a method and a device for calculating dynamic reserves of a gas reservoir. The method is used for the water-sealed gas reservoir and comprises the following steps of: acquiring reservoir physical property parameters of the gas reservoir and production dynamic data of the gas reservoir; acquiring capillary pressure difference between the water-sealed gas reservoir and a main gas reservoir according to the reservoir physical property parameters; acquiring average formation pressure of the water-sealed gas reservoir according to the reservoir physical property parameters, the production dynamic data and the capillary pressure difference; acquiring a natural gas deviation coefficient of the gas reservoir according to the reservoir physical property parameters, the production dynamic data, the formation pressure of the water-sealed gas reservoir and relative density of natural gas; determining an original geological reserve model of the gas reservoir according to an oil-gas material balance |
