Key words
: well construction, permafrost, Casing integrity, casing and intercolumny annulus, complications of the cementing process, lightweight aerated erosion buffer fluid, lightweight aerated slurry, normal density plugging, composite pillars of fluids, designcementing technology, innovative cementing technology.

The article is devoted to the solution of the problem of increasing the quality of cementing of all casing columns in wells of the Tevlinsko-Russkinskoye field with the prevention of various complications.It is shown that a variety of complications that occur with high probability in different periods of time with widely and practically universally applied design technology of cementing all casing columns are natural, since they are man-made.In this connection, the design technology does not provide protection of the subsoil and the environment, primarily due to the leakage of casing and intercolumnyannulus, as well as the isolation of fluid-bearing horizons from each other, from permeable rocks and the surface of the day.Only the use of innovative powdered mixtures and technologies for their practical application will eliminate the occurrence of complications of the cementing process in the conditions of this field and other fields with similar mining and geological conditions.
