PORTABLE METERING STATION OF EXTRACTED WELL LIQUID Russian patent published in 2015 - IPC E21B47/10 

FIELD: oil and gas industry.

SUBSTANCE: portable metering station of the extracted well liquid includes a vertically installed cylindrical housing that is stepped and composite - upper and lower, which are fixed with a flange connection. In the upper part of the housing there installed is a separating element - hydraulic cyclone provided with a mist eliminator. A gas control valve is installed above the mist eliminator and interconnected with a gas outlet branch pipe. The latter is interconnected with a gas line with connected measuring instruments - a pressure sensor, a pressure gauge and a weight gauge. An inlet liquid branch pipe is interconnected tangentially with the hydraulic cyclone. An outlet liquid line is provided with a mass meter, a moisture meter and a sampling unit, one of which has manual control. A temperature sensor, an information collection and storage unit, which is electrically connected to the measuring instruments, as well as a drain branch pipe with shutoff valves. The gas control valve operates for closing with a pusher of a float stem, which is installed in a sleeve, with a cone-shaped cover plate mounted concentrically and with a gap inside the lower housing. In the sleeve walls on the level of the cover plate base there are side openings connecting the cavity of the hydraulic cyclone to the cavity of the lower housing. Each of the gas and liquid outlet lines in the zone of interaction with a common manifold is provided with check valves.

EFFECT: improvement of operating characteristics.
