FIELD: mining.SUBSTANCE: in the method for assessment of wettability there is a principle realised for spontaneous formation of liquid drops on rock sample surface as a result of vapour condensation. For this purpose the rock sample cooled down to temperature below dew point is placed into a medium with liquid vapours, and the wetting angle of drops produced as a result of condensation is measured.EFFECT: increased accuracy of assessment of wetting properties of porous rocks, possibility of differentiated assessment of wettability of rock-forming rock minerals, elimination of listed disadvantages of above methods.2 cl, 2 dwg |
