| description | The utility model relates to a device for predicting the capacity of a fractured-porous oil reservoir. A basic parameter acquisition unit is used for acquiring parameters including a matrix permeability Km and a fracture permeability Kf; the permeability acquisition unit is used for obtaining a fractured-porous dual-medium reservoir permeability KA according to the matrix permeability Km and the fracture permeability Kf acquired by the basic parameter acquisition unit; a stratum fracture generating closed radius acquisition unit is used for obtaining a stratum fracture generating closed radius rf based on permeation fluid mechanics and through the permeability acquired by the permeability acquisition unit and the parameters acquired by the basic parameter acquisition unit; an oil reservoir output and bottom hole pressure relation unit is used for obtaining the relation between the fractured-porous oil reservoir output and the bottom hole pressure based on internal and external boundary conditions and reservoi |
