FIELD: oil and gas industry.
SUBSTANCE: lubricating device comprises a station of sealing lubricant supply, an injector for supply of a reagent - an inhibitor of hydrate formation, a sealant, comprising calibrated bushings and a tail. The injector is made in the form of a jacket sealant installed concentrically at the tail, where a perforated cartridge is installed with stuffing of a porous material, being the extension of the tail and equipped with a seal, which locks the circular channel between the jacket and the tail.
EFFECT: improved protection of a lubricating device against formation of ice-hydrate plugs in a sealant, prevention of complications caused by freezing of a geophysical cable to walls of calibrated bushings.
