Shale condensate gas reservoir dynamic reserve calculation method and device and storage medium

The invention discloses a shale condensate gas reservoir dynamic reserve calculation method and device and a storage medium. The method comprises the steps that reservoir parameters and production dynamic data of a shale condensate gas reservoir are acquired; according to the reservoir parameters and corresponding data in the production dynamic data, obtaining a shale matrix shrinkage coefficient, a proportion of natural gas in well flow, and a well flow cumulative yield and a condensate gas deviation coefficient corresponding to the average formation pressure of each shale condensate gas reservoir; determining an original geological reserve model of the shale condensate gas reservoir according to the reservoir parameters, the production dynamic data, the shale matrix shrinkage coefficient, and the well flow cumulative yield and condensate gas deviation coefficient corresponding to the average formation pressure of each shale condensate gas reservoir; converting the original geological reserve model into a li
