DEVICE FOR MEASUREMENT OF YIELD OF GAS AND FLUID OF OIL WELLS Russian patent published in 2011 - IPC E21B47/10 

FIELD: oil and gas production.

SUBSTANCE: device is equipped with vertical cylinder reservoir, with inlet and outlet fluid lines made in form of siphon, with gas line with pressure gauges and sensors of temperature phase, and with computer unit with electron clock. The device includes a hydraulic lock, a common line communicating it with a gathering main, a fluid volume counter and a lock valve. Also, the lock valve is automatic, bypass, two-phase, and of discrete action with magnetic fixation of its end positions. Also, the same as the counter, the lock valve is mounted on the common line after the counter before the common line enter into the gathering main. The outlet fluid line by means of a descending branch of a bellows and the gas line are communicated with the hydraulic lock. The pressure gauge and temperature sensor are installed on the gas line.

EFFECT: raised reliability of device at measuring yield; simplification of design.
