Abstract

Способ вскрытия незатвердевшего интервала в подземной формации включает стадию затвердевания. Стадию затвердевания выполняют закачиванием водного раствора коллоидных частиц с рН модификатором и/или модификатором ионного состава. Образуется плотный гель, который удерживает микрочастицы вместе. За отверждением следует гидравлический разрыв. Отклонение к областям более низкой проницаемости может быть увеличено при использовании микрометрических частиц.
