FIELD: oil and gas production.
SUBSTANCE: method for doing repair-isolation works under conditions of intense absorption includes injection of phosphogypsum suspension and liquid sodium glass into absorption interval. At the same time edging of 1-3 m3 of oil-acid emulsion is previously pumped into well, and then serially equal amounts of liquid sodium glass and 50% aqueous suspension of phosphogypsum are pumped in 1-4 cycles with total volume of single cycle from 4 to 8 m3 with intermediate pumping of fresh water buffer in between.
EFFECT: improved efficiency of repair-isolation works under conditions of intense absorption.
