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

Задачей изобретения является создание способа, позволяющего повысить прочность водоизолирующего барьера путем фиксации его в призабойной зоне водоносной части пласта оторочкой магнитоактивной суспензии, что проявляется в увеличении градиента давления возобновления фильтрации. Для этого в способе ограничения притока воды в скважину путем нагнетания в пласт изолирующего состава в виде пены перед нагнетанием его в пласт нагнетают раствор полимера, а после нагнетания - магнитоактивную суспензию и одновременно с нагнетанием последней в скважину опускают магнит на уровень призабойной зоны водоносной части пласта.The objective of the invention is to provide a method to increase the strength of the waterproofing barrier by fixing it in the bottom-hole zone of the aquifer of the formation with a rim of a magnetically active suspension, which manifests itself in an increase in the pressure gradient of the resumption of filtration. To this end, in the method of limiting the flow of water into the well by injecting an insulating composition in the form of foam into the formation, a polymer solution is injected into the formation before injection into the formation, and after injection, the magneto-active suspension and simultaneously with the injection of the latter, the magnet is lowered to the bottomhole level of the aquifer of the formation.
