Abstract

1. Применение маточного раствора сульфата аммония от упарки воднокислотного стока производства капролактама, содержащего не менее 41 мас.% сухого остатка, не менее 2.1 мас.% аминоорганических кислот в пересчете на аминокапроновую кислоту и имеющего pH выше 4.4, в качестве реагента для обработки нефтяного пласта. ! 2. Способ обработки нефтяного пласта с использованием реагента по п.1, отличающийся тем, что в зону нефтяного пласта закачивают реагент по п.1 и с водным раствором электролитов, и/или с органическим растворителем, при этом химреагенты закачивают в пласт в порядке и сочетаниях, определяемых состоянием призабойной зоны пласта скважины. 1. The use of a mother liquor of ammonium sulfate from an evaporation of an aqueous acid runoff of caprolactam production containing at least 41 wt.% Dry residue, at least 2.1 wt.% Amino acids in terms of aminocaproic acid and having a pH above 4.4, as a reagent for treating an oil reservoir . ! 2. The method of processing an oil reservoir using a reagent according to claim 1, characterized in that the reagent according to claim 1 is injected into the zone of the oil reservoir with an aqueous solution of electrolytes and / or with an organic solvent, while the chemicals are pumped into the reservoir in the order and combinations determined by the state of the bottom-hole zone of the wellbore.
