FIELD: gas production industry. SUBSTANCE: according to method, for installing cement bridge, lowered into well are pump-compressor pipes. Then, injected into well is calculated amount of cement slurry. Pump-compressor pipes are removed from cement slurry. Cement-slurry is subjected to curing until hardening up to 0.2-0.8 MPa. Pump-compressor pipes are used together with device intended for removing surplus size of cement bridge and up to resting against created cement bridge. Removal of surplus amount of cement bridge is effected by crushing of cement stone by injecting washing liquid at flow rate of 6-8 l/s and pressure of 45-50 atm. Application of aforesaid method allows for enhancing efficiency in creation of cement bridge. EFFECT: higher efficiency.
