摘　　要：A model of double medium aquifer is briefly introduced in this paper, a partial differential equation about seepage motion derived by the tidal stress in the model layer is deduced. Compared this equation with Boulton equation used in the unconfined aquifer, a new lagging supply water term is obtained, which establish the physical basis for interpreting the phase delay phenomena of well water level caused by the solid tide. By analyzing the partial differential equation, it is found that this lagging supply term is related with the fluctuation of tide occurred in the deep aquifer.A model of double medium aquifer is briefly introduced in this paper, a partial differential equation about seepage motion derived by the tidal stress in the model layer is deduced.
