Abstract
Жидкость для обработки ствола скважины включает по меньшей мере две фазы, включающие жидкую фазу и твердую фазу. Твердая фаза представляет собой порошкообразный твердый материал с нанесенным покрытием из полимера, являющегося продуктом реакции между полиэфирамином на основе простого эфира и диальдегидным сшивателем. Предпочтительно полиэфирамином на основе простого эфира является диамин, а более предпочтительно соединение выступает в роли замедлителя гидратации глин. Диальдегидный сшиватель вступает в реакцию с производным полиэфирамина на основе простого эфира и формирует полимерный материал, образующий покрытие на твердой фазе. Полимер, по существу, солюбилизируется, когда значение рН рабочей жидкости имеет величину, меньшую приблизительно 7.
