FIELD: oil and gas industry.
SUBSTANCE: perforated joint with centraliser and landing ring is run-in at tubing to production string. Gelling agent and soil stabiliser are pumped one by to tubing one through by-pass plug and then mixing of gelling agent and soil stabiliser is made during liftup of the perforated joint at tubing. At that mixing is made under pressure in order to receive grouting compound with required setting time.
EFFECT: allows expansion of dosing range at joint liftup at tubing with simultaneous pumping of gelling agent through radial holes and receiving grouting compound with different physical and chemical properties due to possible regulation of grouting components dosing by surplus pressure.
