BOREHOLE SEPARATOR AND METHOD OF FLUID SEPARATION HEREBY Russian patent published in 2012 - IPC E21B43/38 

FIELD: oil-and-gas industry.

SUBSTANCE: set of inventions is intended for oil field equipment in mechanised oil extraction. Proposed separator comprises connection head, body, slime tube and separation unit made up of hollow auger with shaped spiral. Gas discharge openings are made under said spiral, all over its length. Separator body top section is communicated with connection head via gas discharge head and, at least, one intake head. The latter has intake channels and borehole fluid separator. Note here that separator body houses auger case. The latter is composed of hollow cylinder with slot cutouts for removal of mechanical impurities from separation unit into chamber between separator body and auger case. Separator is furnished with guide vane arranged under separation unit and provided with channels to feed mechanical impurities into slime tube and those to feed fluid from separation unit to branch pipe. Hollow auger top section, not surrounded by shaped spiral, has gas release openings.

EFFECT: higher efficiency of oil production.
