FIELD: oil and gas industry.
SUBSTANCE: method involves separation of oil-gas-water fluid contained in a measuring cylinder using chemical reagents for oil and water with gas emission, measurement of height of liquid column, hydrostatic pressure, emptying of the measuring cylinder, measuring current values of differential pressure and levels of oil-gas-water fluid, oil-water fluid, oil, calculation of oil and water density. At that, volume content of water is calculated by a mathematic formula, and weight content of water is calculated as difference between the value of differential pressure of water in the measuring cylinder and the value of differential pressure of oil-water fluid in the measuring cylinder.
EFFECT: increased measurement accuracy for determination of parameters of oil-gas-water mix.
