FIELD: oil and gas industry. ^ SUBSTANCE: lubricator includes housing with axial channel and connecting flange, in the head of which there installed is gland with rope sealing inside it, pressure nozzle of axial constriction of seal, and a scraper retained with a rope, which is intended to clean oil-product deposits off internal tube surface. Use of oil bath fixed on pressure nozzle for rope lubrication and seal constriction with cleaning oil-scraper ring above it. ^ EFFECT: decreasing sliding friction of rope in lubricator and its rolling friction on winch drum, preventing production wear of rope in lubricator and jamming on winch drum, improving reliability and life time of lubricator operation and reducing the outage time of the well. ^ 7 cl, 2 dwg, 1 tbl |
