A two-phase spatially inhomogeneous system of point-like particles of the ion-dipole mixture in porous media with a sharp interfacial plain is considered. A replica nonuniform Ornstein-Zernike equation is used for the discription of screening effects of electrostatic interactions. The expressions for two- and one-particle screened potentials are been obtained and their asymptotics is studied as well.
