FIELD: oil and gas industry.
SUBSTANCE: invention relates to devices for measurement of water-content of produced oil in downhole zone. Proposed device comprises two pressure transducers arranged at fixed distance from each other in tubing string of maximum permissible diameter inside oil producing well. At that, the tubing with pressure sensors is installed in the middle part of the flow column, which connects the receiving openings of the electric-centrifugal pump to the oil formation roof, wherein below and above the pipe with pressure sensors there used is a tubing of smaller diameter to provide a turbulent mode of movement of well products in them, and in the pipe with sensors pressure is higher than pressure of oil saturation with gas.
EFFECT: providing homogeneity of the measured medium and constant correspondence of the gas-liquid composition between the measuring sensors to the composition of the formation products.
