FIELD: oil-and-gas industry.
SUBSTANCE: proposed method comprises filling measuring tank with well product via inlet valve to maximum level With water-oil mix reaching maximum level, tank inlet valve is closed to let free gas to escape from fluid. Water-oil mix discharge is defined by the rate of tank filling the volume of separated fluid. Inlet valve is opened to displace the product from tank into manifold for time interval equal to previous period of tank filling with well product. Gas is gradually derived and forced into manifold by compressor. Gas bleeding is performed via pressure control valve at compressor inlet to atmospheric magnitude. Associated gas discharge is defined by compressor output, time of pressure decrease in calibrated vessel to atmospheric values and volume of vessel filled at the time with gas phase.
EFFECT: higher accuracy of measurement and definition of oil gas factor with allowance for dissociated gas.
