FIELD: oil and gas production.
SUBSTANCE: composition for water insulation in gas-bearing seam contains, wt %: as surface active substance hydrophobisator Neftenol ABR 1-10, film forming hydrophobisator 1-20, as liquid hydrocarbons - volatile hydrocarbon solvent - the rest. Also film forming hydrophobisator is chosen from a group including black oil and viscous oil, volatile hydrocarbon solvent - from group including gas condensate, distillate of gas condensate, gas benzene and petroleum ether or their mixture.
EFFECT: increased efficiency of water insulation and decreased destruction of bottomhole zone of seam.
