Abstract
1. Способ изоляции проницаемого пласта, включающий подачу в пласт водного раствора электролита-коагулянта с последующей подачей водной дисперсии полимера, способной к электролитной коагуляции. ! 2. Способ по п.1, отличающийся тем, что в качестве водной дисперсии полимера используют полиуретановую или акрилполиуретановую дисперсию, а в качестве водного раствора электролита-коагулянта - водный раствор соли одно-, двух- или трехвалентного металла, например хлористого натрия, хлористого кальция или сернокислого алюминия в концентрации от 10 мас.% до концентрации предельного растворения. 1. A method of isolating a permeable formation, comprising supplying an aqueous solution of an electrolyte-coagulant to the formation, followed by an aqueous dispersion of a polymer capable of electrolyte coagulation. ! 2. The method according to claim 1, characterized in that a polyurethane or acrylic polyurethane dispersion is used as an aqueous polymer dispersion, and an aqueous solution of a salt of one, two or trivalent metal, for example sodium chloride, calcium chloride, is used as an aqueous solution of an electrolyte-coagulant or aluminum sulfate in a concentration of from 10 wt.% to the concentration of the maximum dissolution.
