DEVICE FOR MEASURING RELATIVE PHASE PERMEABILITIES IN POROUS MEDIUM AT ITS THREE-PHASE SATURATION Russian patent published in 2024 - IPC G01N15/08 E21C39/00 

FIELD: measurement.

SUBSTANCE: invention relates to devices for determining phase permeability in a porous medium. Device comprises first circulation pump (1), feedback (2), second and third circulation pumps (3, 4), core holder (5) for placement of analysed sample of porous medium, dry-air thermostat (6), three-phase measuring separator (7) equipped with ultrasonic sensors, system (8) for creation and monitoring of rock pressure, supply (9) and discharge (10) pipelines, system (11) for measuring saturation of a sample of a porous medium with a third fluid, system (12) for measuring saturation of a porous medium sample with a first or second fluid, a differential pressure gauge (13). Three-phase measuring separator (7) is divided into interconnected upper (14), middle (15) and lower (16) sections. Upper section (14) is intended for the first (light) fluid, middle section (15) – for the second (middle) fluid, and lower section (16) – for the third (heavy) fluid.

EFFECT: possibility of reliable determination of phase permeability in porous medium at its three-phase saturation.
