Claims (2)

1. Способ изоляции обводнившихся участков пласта, включающий закачку в пласт водных растворов сернокислого натрия и хлористого кальция, отличающийся тем, что предварительно в пласт закачивают дисперсионный состав с концентрацией дисперсной фазы 0,3 - 3%, а в водный раствор сернокислого натрия вводят ПАВ-щелочные добавки до концентрации их 0,3 - 10%, при этом используют водные растворы сернокислого натрия и хлористого кальция высокой концентрации.1. The method of isolation of waterlogged sections of the reservoir, including the injection into the reservoir of aqueous solutions of sodium sulfate and calcium chloride, characterized in that the dispersion composition with a concentration of the dispersed phase of 0.3-3% is preliminarily injected into the reservoir, and a surfactant is introduced into the aqueous solution of sodium sulfate alkaline additives to a concentration of 0.3 to 10%, while using aqueous solutions of sodium sulfate and calcium chloride of high concentration. 2. Способ изоляции обводнившихся участков пласта по п. 1, отличающийся тем, что водные растворы сернокислого натрия и хлористого кальция закачивают в пласт циклически - в несколько приемов. 2. The method of isolation of waterlogged sections of the formation according to claim 1, characterized in that the aqueous solutions of sodium sulfate and calcium chloride are pumped into the formation cyclically in several stages.
