Abstract
Способ проведения водоизоляционных работ в скважине, включающий закачку в изолируемый пласт суспензии водонабухающего полимера, отличающийся тем, что суспензию водонабухающего полимера закачивают в три цикла: в первом цикле в воду хлоркальциевого типа с минерализацией 120 г/л закачивают водонабухающий полимер В 50 Э, во втором цикле в воду хлоркальциевого типа с минерализацией 60 г/л закачивают водонабухающий полимер В 105, в третьем цикле в пресную воду закачивают водонабухающий полимер В 210.A method of carrying out waterproofing work in a well, comprising injecting a suspension of a water-swellable polymer into an insulated formation, characterized in that the suspension of a water-swelling polymer is pumped in three cycles: in the first cycle, calcium chloride-type water with a salinity of 120 g / l is pumped into a water-swelling polymer B 50 Oe, in the second in a cycle of calcium chloride type water with a mineralization of 60 g / l, a water-swelling polymer B 105 is pumped; in the third cycle, a water-swelling polymer B 210 is pumped into fresh water.
