FIELD: possible use for determining water presence level in product of oil wells.
SUBSTANCE: method for measuring mass concentration of water in water-oil-gas mixture includes taking of a sample of water-oil-gas mixture in hermetic cylinder-shaped vessel with given volume V and height H and measurement of hydrostatic pressure P1 at fixed values of temperature T and pressure Pa in aforementioned vessel. After measuring of hydrostatic pressure volume of vessel hollow is decreased until full solution of gas and hydrostatic pressure P2 is measured, and mass concentration of water W in water-oil-gas mixture is determined in accordance to mathematical expression 
, where g - free fall acceleration.
EFFECT: improved precision of measurements of mass concentration of water in liquid due to prevented influence of gas separation.
