| description | The invention discloses a reservoir large-aperture porosity calculation method and device, electronic equipment and a medium. The method can comprise the following steps: calculating the large-aperture porosity of each rock core sample; establishing a first fitting relationship between the large-aperture porosity and the permeability of the sample; calculating the large-aperture porosity of the target area according to the first fitting relation and the permeability of the target area; calculating a porosity difference, and establishing a second fitting relationship between the large-aperture porosity of the target area and the porosity difference; and calculating the large-aperture porosity of the target well according to the porosity difference of the target well and the second fitting relationship. According to the method, the large-aperture porosity is calculated according to the permeability through the good correlation between the permeability and the large-aperture porosity, then the calculation relati |
