FIELD: oil machinery, particularly arrangements for separating materials produced by the well.
SUBSTANCE: gas separator comprises body with inlet orifices, shaft, auger assembly and centrifugal separation unit serially arranged on the shaft, as well as liquid and gas discharge channels. The separator has additional auger unit connected to the shaft so that lower end of additional auger unit is aligned with liquid discharge channel outlet or is located over the channel. Part of gas discharge channel is defined by cavity having additional auger unit, which prevents reservoir liquid ingress from hole annuity into gas discharge channel.
EFFECT: increased pumping plant operation stability and decreased gas phase content in liquid to be pumped out.
