FIELD: oil-and-gas industry.
SUBSTANCE: borehole insulation work compositions can be used for water flow insulation, for between borehole gas flow and other maintenance works. Borehole insulation works viscouse-elastic composition contains wt %: polyvinyl spirit 2.9-6.9, triethanolamine titanate - TEAT 1 0.3-0.6, GKJ-10 or GKJ-11 0.1-0.3, aluminium powder 0.1-0.4, the rest is water.
EFFECT: borehole insulation works efficiency increase.
