FIELD: oil and gas production.
SUBSTANCE: in method for liquidation of absorption zones in well, including simultaneous pumping of two flows - liquid carrier with phosphogypsum and with liquid sodium glass, liquid carrier is represented by clayey drilling solution, containing carboxymethylcellulose or carboxymethylated starch, and specified pumping is carried out in parallel with mixing of flows prior to injection into isolated interval of reservoir.
EFFECT: improved efficiency of repair-isolation works under conditions of intense absorption as a result of elimination of complications when doing repair-isolation works by development of sedimentation-stable flows and reduction of structuring time in zone of disturbance.
