FIELD: transportation of water-oil-gas mixtures. SUBSTANCE: mixture is delivered from collecting station through pipeline and through unit for cleaning it of mechanical impurities to the suction end of double-screw pump from its outlet, into a transport line. At the pump outlet the mixture is divided into liquid and gas phases by means of flow divider. The other part of liquid phase is returned through bypass pipeline with control gate to pump suction so as to maintain total gas content at the suction side below the stalling limit. EFFECT: higher efficiency. 1 dwg
