Abstract
This paper describes the results of the experimental investigations of the processes of capillary filtration through porous media of natural rocks and water-protecting coatings of clay-layer. Although the physical mechanisms of capillary filtration in porous media seem to be understood, the macroscopic description of them remains a problem as the capillary filtration dynamics depends on the geometrical dimensions of media with respect to the size distribution function of pores and throats. In particular, we are interested in the studies of the processes of capillary filtration in media with complex shape of a size distribution function of pores and throats to estimate the dominant forces (viscous or capillary) which determines the gas and water flow rate in natural rocks and clays.
