FIELD: oil and gas industry.
SUBSTANCE: curable solution of resin and cement grouting are subsequently pumped. The pumping is performed through the tubing string, the shoe of which is installed as close as possible to the perforation interval, but nor closer than 20 m. The resin cured with a hardener with alkaline or neutral pH values is pumped as resin.
EFFECT: increased strength of plugging stone is achieved due to minimisation as to volume of mixing zone of resinous and cement grouting above the perforation interval.
