Abstract
FIELD: oil production industry, methods of stratum waters inflow in oil wells in particular. SUBSTANCE: aim is to increase strength of water insulating barrier using its fixation in critical zone of water carrying part of stratum by trimming it with magnetically active suspension, that causes increase of pressure gradient of filtration resumption. Method of limitation of water inflow in oil well provides for injection in stratum of insulation composition in the form of foam. Before its injection in stratum polymer solution is injected there. After injection of insulation composition in the form of foam magnetic active suspension is injected in stratum and simultaneously with injection of the latter permanent magnet is lowered in well down to level of critical zone of water carrying part of stratum. EFFECT: increased strength of water insulating barrier in stratum. 1 tbl
