FIELD: oil-and-gas industry.
SUBSTANCE: proposed process comprises displacement of fluid saturating the rocks at spinning of centrifuge. Note here that before centrifuge spinning the displacement fluid if forced in centrifuge sealed core holder to the level higher than forecast maximum capillary pressure in the rock. Besides, this invention discloses the device used for process implementation.
EFFECT: higher capillary pressure in low-permeability rocks.
