DEVICE FOR DETERMINATION OF PHASE PERMEABILITY Russian patent published in 2016 - IPC E21B49/00 

FIELD: oil and gas industry.

SUBSTANCE: proposed device comprises the following components. The core holder houses the rubber collar with the specimen to be analyzed. The thermostat maintains the constant temperature in said specimen. The plunger pumps feed the oil and fluid at strata pressure. Intermediate tanks keep working fluids and the pump develops the strata pressure. Pipelines feed and discharge the working fluids. There are containers with working fluids, counter pressure controller, volumetric flask to measure fluid pressure at the core holder outlet and pressure transducers. Differential pressure gage measures the pressure difference at analyzed specimen. Note here that intermediate tank with water is provided with media separator composed of the magnet fitted in the polymer washer. Note here that the magnet-to-polymer weight ratio is selected to make the total separator density smaller than water density and higher than used oil density. Two contactless magnetic transducers are fitted at extreme lower and upper parts of said intermediate tank.

EFFECT: longer life of plunger pumps of phase permeability determination plants.
