Volcanic rock high-porosity low-permeability reservoir reserve calculation method based on multi-factor permeability

The invention discloses a volcanic rock high-porosity low-permeability reservoir reserve calculation method based on multi-factor permeability. According to the method, logging data, coring data and geological data of a target well are utilized, the porosity and permeability of a core of the target well are measured, a porosity and permeability cross plot is drawn, the relation between the porosity and the permeability in the target well is established, the influence of a high-porosity and low-permeability reservoir on reserve calculation is analyzed, and then the influence of a pore structure on seepage characteristics is anlayzed according to a scanning electron microscope graph of the core of the target well, the reserves of a target well is calculated by using single-factor permeability and multi-factor permeability based on a volumetric method, reserves calculation results adopting the single-factor permeability and the multi-factor permeability are compared, the difference of calculation results of diff
