Аnnotation: Experiments for the estimation of electrokinetic parameters porous sand rocks were carried out by stationary single-flow of water and stationary water-oil mixes. The values of ζ-potentials of double electric layer, streaming potential and electroosmotic coefficient were determined. These estimations agree with other known experimental works. Monotonic decreasing of electrokinetic parameters during the increasing of pressure gradient was fixed by two-phase flow experiments with the change of sign. This effect account for specific absorption potential-formed ions and partial hydrofobization of the mineral surface.
