Claims (2)

1. Способ разработки нефтяных месторождений заводнением путем селективной изоляции пластов, включающий закачку в пласт гелеобразующей оторочки на основе силиката натрия - жидкого стекла, аммиачной селитры, анионного ПАВ и пресной воды, отличающийся тем, что в получении гелеобразующей оторочки вместо анионного ПАВ используют реагент РДН-0 по ТУ 2458-001-21166006-97 при следующем соотношении компонентов, мас.%:1. A method of developing oil fields by waterflooding by selective isolation of formations, including injecting into the formation a gel-forming rim based on sodium silicate - water glass, ammonium nitrate, anionic surfactant and fresh water, characterized in that RDN-reagent is used instead of anionic surfactant to produce a gel-forming rim 0 according to TU 2458-001-21166006-97 with the following ratio of components, wt.%: Силикат натрия - жидкое стекло 10,0 - 50,0Sodium silicate - water glass 10.0 - 50.0 Аммиачная селитра 5,0 - 10,0Ammonium nitrate 5.0 - 10.0 Реагент РДН-0 1,0 - 10,0Reagent RDN-0 1.0 - 10.0 Пресная вода ОстальноеFresh Water Else 2. Способ по п.1, отличающийся тем, что для нефтяных месторождений с высокой минерализацией пластовых вод до и после закачки гелеобразующей оторочки в нагнетательную скважину закачивают пресную воду в объемах равных объему закаченной в пласт гелеобразующей оторочки.2. The method according to claim 1, characterized in that for oil fields with high salinity of formation water, before and after the injection of the gel forming rim, fresh water is pumped into the injection well in volumes equal to the volume of the gel forming rim injected into the formation.
