The trapping of bubbles during the impregnation of micromodel of dual scale porisity media by a liquid are experimentally studied. The micromodel of a porous medium is formed by a system of cylindrical pins spatially ordered in a flat microchannel. It is shown that the content of bubbles in a porous medium after impregnation depends on the capillary number and wettability of the pore surface. The proposed approach can be used to solve the practically important problem on studying and selecting optimal mechanisms to control the impregnation process of porous materials to minimize the total amount of trapped bubbles.
