The invention provides a heterogeneous reservoir physical property parameter calculation method and device based on conventional logging. The method comprises the following steps: constructing a triple pore structure interpretation model of a heterogeneous reservoir; calculating the total porosity of the triple-pore structure interpretation model by using a neutron density intersection method; calculating the porosity of matrix pores through acoustic logging; calculating the porosity of the crack pores according to the total porosity and the porosity of the matrix pores; and determining the porosity of the pores according to the total porosity and the fracture porosity. According to the method, the potential of conventional logging information for evaluating the physical property of the heterogeneous reservoir is fully excavated, so that the purpose of evaluating the physical property parameters of the heterogeneous reservoir by using conventional logging series is achieved, the physical property of the heter
