DEVICE FOR PERMEABILITY TO PHASE DETERMINATION Russian patent published in 2017 - IPC E21B49/00 G01N15/08 

FIELD: oil and gas industry.

SUBSTANCE: device, containing the core holder with the test sample mounted in the rubber collar, the thermostat, that provides the constant temperature in the test sample, the plunger pumps for supplying the working fluids (oil and water) into the test sample at the formation pressure, the rock pressure pump, the pipelines for supply and removal of the working fluids, the back pressure regulator, the containers with working fluids, the measuring flask for measuring the liquid level at the exit from the core holder, the pressure sensors, the differential pressure gauge for measuring the pressure drop in the test sample, the sample resistance meter, contains the unit for mixing the working fluids, installed in the inlet pipeline.

EFFECT: increase of the sample electrical resistance measuring accuracy, which in its turn provides the increase of the water saturation determination accuracy.
