description	The invention belongs to the technical field of oilfield development, and particularly relates to a low-permeability reservoir pressure drive development pressure wave conduction and oil-water migration rule simulation method. The method comprises the following steps: acquiring percolation related parameters of a target reservoir; the method comprises the following steps: establishing a seepage model corresponding to an isotropic uniform incompressible medium on the basis of a Buckley-Leveett theory; solving the seepage model based on a finite difference method, and performing grid division and time step setting on a target reservoir; establishing a difference equation of pressure and saturation; solving relative permeability of oil and water under different water saturations through interpolation relative permeability data, and substituting the relative permeability into the established difference equation; and drawing pressure and saturation distribution in preset time. By means of the method, the pressure
