Key words:cementing of casing strings, aerated cementing slurry, aerated abrasive buffer solution.

The authors present a technology and materials for the cementing of various casing strings, including the use of aerated powder mixtures. Following laboratory testing and field studies, it was established that lightweight aerated powder mixtures including factory-made materials, can perfectly be used for first cementing of casing strings in conditions of low for mation pressure and temperature difference.
