FIELD: oil and gas industry.

SUBSTANCE: invention relates to oilfield equipment, in particular to submersible gas separators intended for separating gas from formation fluid, and can be used for oil production with large gas factor values. Vortex gas separator contains housing with protective sleeve, input module, rotating shaft with axial swirling wheel, pressure unit consisting of working axial wheel and guiding apparatus mounted on shaft, vortex chamber and separating head. Axial twisting wheel is installed between guide apparatus and vortex chamber. Working axial and swirling wheel are made to coincide in configuration and are cylindrical or conical bushing with central bore for the shaft, on which from two to four blades are fixed, having form of variable pitch spiral, making no more than one revolution around the axis.

EFFECT: high separating properties of gas separator, including at high flow rates, simplicity of construction and manufacturability in manufacturing.
