FIELD: oil-and-gas industry.
SUBSTANCE: proposed method of cementing comprises injection of cementing composition in underground stratum. Note here that cementing composition comprises: ground Portland cement is mixed with burned shale, cement kiln dust, natural puzzolana and water and solidified. Used cementing composition contains aforesaid components. Invention is developed in dependent claims.
EFFECT: controlled flow characteristics, solidification interval, higher strength of cement stone.
