FIELD: mining.
SUBSTANCE: composition for killing oil, gas and gas condensate wells includes dispersion medium, emultal, waterproofing silicon-organic liquid WSL-11N, alumo-silicate microspheres ASM and mineralised water, as dispersion medium diesel fuel is used, and as mineralised water - at least 10% water solution of sodium chloride - NaCl is used, at following ratio of components, % wt: diesel fuel 27.0-30.0, emultal 4.0-5.0, ASM 13.0-20.0, WSL-11N 2.5-3.0, mineralised water - the rest.
EFFECT: facilitating minimal negative effect on filtering-capacity properties of rock-reservoirs, optimal viscosity, stricture-mechanical properties, thixotropy of structure and minimal, up to zero filtration, into bottomhole zone of reservoir.
