Abstract

On the basis of earlier experiments it is known that the flow of W/O emulsion in the slit-like model and in capillaries of different diameters leads to the fact that the mass transfer of the emulsion ceases with time at with a constant pressure drop. This phenomenon was called as a dynamic blocking effect. In the paper the radial-expanding flow of W/O dispersion in the fracture model and filtration flow in the core were studied at constant pressure drop for the presence of the blocking.
