INSTALLATION FOR DEFINITION OF GAS FACTOR AT COLLAR OF OIL PRODUCER Russian patent published in 2010 - IPC E21B47/00 

FIELD: oil and gas industry.

SUBSTANCE: installation includes sample sorter of liquid-gas mixture in the form of disk with axial channel, allowing radial off-take, vertically implemented gas buster, intercommunicated to sample sorter by means of connecting tube. In the bottom part of cavity of vertical gas tank it is installed swirler of gas-liquid mixture. Swirler is implemented in the form of installed in casing training multithread worm insert, fixed at the top by clutch, internal surface of which is implemented as conical. Swirler of gas-liquid mixture is installed on connecting branch, fixed on the bottom of vertical gas tank and is connected by pipe to sample sorter. Lower than swirler of gas-liquid mixture there are installed exhaust slack disks. In the top part of cavity of vertical gas tank over the swirler of gas-liquid mixture it is installed gas swirler in the form of horizontal partition with openings and radially located over them blades with angle of its inclination opposite to direction of channels of worm insert of swirler of gas-liquid mixture. Bottom part of cavity of vertical gas tank is intercommunicated with butt part of cavity of horizontally implemented tank, in bottom part of cavity of which it is installed turbulence promoter of partly separated gas-liquid mixture, in the form of partitions, located lower than installed level of partly separated gas-liquid mixture in horizontally implemented tank. In top part of cavity of horizontally implemented tank, opposite to turbulence promoter it is installed training end cap for supplying of light gas from top cavity of vertical knockout box into cavity of horizontally implemented tank by means of gas-intake pipeline. The other butt part of cavity of horizontally implemented tank is intercommunicated with separating chamber of phases flow. In separating chamber it is located valve - regulator of liquid level in chamber, sealing part of which is located in cavity of gas-outlet branch of chamber, on which it is installed counter of gas amount. Additionally separating chamber in the bottom part is intercommunicated with hydraulic hitch which is installed in measuring tank, and measuring tank is intercommunicated to sample sorter of gas-liquid mixture.

EFFECT: invention provides accuracy increasing of gas factor definition of well ensured by deep separation of gas-liquid mixture by phases and regularity of measurement process of phases volumes of gas-liquid mixture sample.
