DEVICE TO MEASURE YIELD OF OIL AND GAS PRODUCTION WELL PRODUCTS Russian patent published in 2015 - IPC E21B47/10 

FIELD: measurement equipment.

SUBSTANCE: invention relates to systems of automatic control and may be used in the control and management of well production processes in oil, gas and other industries. The device comprises a measuring tank, a weight meter, an inlet pipeline for well production, an outlet pipeline for gas and an outlet pipeline for liquid, equipped by a controlled stop element connected to an electric control circuit. At the same time the device includes an additional measuring tank. The inlet pipeline is equipped with a controlled flow switch, to which both measuring tanks are connected. An additional measuring tank, together with the existing one, is connected to the outlet pipeline for gas, and via an additional controlled stop element with an outlet pipeline for liquid. Cantilever-jammed pipelines are used as inlet and outlet pipelines of each tank. Both the measuring tanks are equipped with liquid level indicators and suspended at weight meters, such as strain gage sensors.

EFFECT: invention is aimed at the reduction of a measurement error, expansion of consumer properties and increased reliability of a device, and makes it possible to measure the yield of well products in a continuous mode, to determine formation water content in well products and to calculate oil net weight.
