FIELD: mining.
SUBSTANCE: composition for isolating water production in well contains, vol %: silicon-organic product 119-296 - 100, isopropyl spirit 7-17, Devonian oil 10-30, sulphuric acid 5.0-20.
EFFECT: increased efficiency of isolating water production due to stabilisation of time of composition solidifying, expanded functionality of composition usage at raised temperature of environment and upgraded degree of selectivity of composition upon pumping into water flooded zones of oil reservoir.
