More Information
Summary:The embodiment of the application discloses a method and apparatus for determining the permeability of a reservoir. The method comprises steps of: determining a pore-throat type division limit based on capillary pressure curve information; determining a pore component division limit corresponding to a rock core nuclear magnetic T2 spectrum based on the pore-throat type division limit, the rock core nuclear magnetic T2 spectrum and a mercury injection pore-throat radius distribution curve; for a specified rock core in a plurality of rock cores, determining the pore components, of a plurality of pore-throat types corresponding to the pore component division limit of the specified rock core, on the nuclear magnetic T2 spectrum of the specified rock core; establishing an incidence relation between the permeability of the specified rock core and the plurality of pore components of the specified rock core; subjecting a nuclear magnetic logging T2 spectrum at a sampling point to oil-gas correction to obtain the nucl
