Key words: expanding composition of cement slurry, additive for increase durability and adhesion, producing well, well completion, oil recovery troubles.

The paper presents the results of research to increase the strength characteristics of expanding composition of cement slurry for casing of wells. Increasing of strength of developed composition of cement slurry is due to the introduction of fine viscous additives the structure of the filling of the pore space in the forming cement stone. When using the developed compositions of modifying additives to cement slurries the strength characteristics of cement stone increases to 2 times.
