Provided is a method for determining effective porosity of high clay-bearing rock core, comprising: acquiring a saturated sample NMR Tspectrum of a high clay-bearing rock core sample, which is measured when temperature of saturated aqueous solution reaches a preset temperature after rock core sample saturated with water being immersed into the saturated aqueous solution and placed and heated in constant temperature and humidity environment; determining a nuclear magnetic total porosity of rock core sample according to the saturated sample NMR Tspectrum; acquiring permeability and NMR Tspectrum of the rock core sample placed in the constant temperature and humidity environment and dried until different time; generating cross-plot of permeability and nuclear magnetic porosity; determining first porosity and second porosity; and determining an effective porosity of the h rock core based on the first porosity, the second porosity, and the nuclear magnetic total porosity.
