ABRASIVE-RESISTANT ROTARY GAS SEPARATOR Russian patent published in 2019 - IPC E21B43/38 

FIELD: oil industry.

SUBSTANCE: invention relates to oil-field equipment, in particular, to submersible gas separators intended for separation of gas from formation fluid, and can be used in complication of production by carrying out abrasive particles. Abrasive resistant rotary gas separator comprises housing, base with holes for liquid passage, rotary shaft with rotor fitted on it, protective sleeve and divider head. Between the rotor and the base there installed is the input grid, which is a fixed guiding device in the form of a bushing with blades fixed on it. Passage cross-section of input grid at the outlet of flow is narrow, and flow area of input grid at output does not exceed total cross-section area of all holes of base.

EFFECT: technical result consists in high structural reliability of device in entire working range of feeds.
