FIELD: oil and gas industry. ^ SUBSTANCE: water influx isolation method involves installation of process shield using the solution containing Mikrodur RU, Sulfatsell, ethylene glycol and water at water-cement ratio of 0.8-0.9. Installation of the above shield is performed in terrigenous formation which is by 5-10 m higher than oil-water contact on the basis of 0.5-2.0 m3 per 1 m of effective formation thickness at the following component ratio, wt %: Mikrodur RU 51.7-54.6, Sulfatsell 0.6, ethylene glycol 1.1, and water 43.7-46.6. ^ EFFECT: improving bottom water insulation, providing the reduction of water content of wells during development of oil and gas deposits. ^ 1 tbl |
