Reservoir type determination method and device, computer equipment and storage medium

The invention provides a reservoir type determination method and device, computer equipment and a storage medium, and belongs to the technical field of oil-gas exploration. The method comprises the following steps: determining a rock sample of a target reservoir; acquiring a capillary pressure curve corresponding to the rock sample, wherein the capillary pressure curve is used for representing a corresponding relation between mercury injection pressure and mercury injection volume of the rock sample; fitting the capillary pressure curve through a first objective function to obtain a first fitting parameter, the first fitting parameter including a first displacement parameter and a first pore morphology parameter; determining a first classification parameter of the rock sample through a second objective function according to the first displacement parameter and the first pore morphology parameter; and determining the reservoir type of the reservoir according to the parameter interval where the first classifica
