Abstract

Состав и способ сокращения времени восстановления после сдвига жидкостных систем катионных, цвиттерионных и амфотерных вязкоупругих поверхностно-активных веществ путем добавления эффективного количества агента для совместного загущения, выбранного из трехблочных олигомерных соединений, имеющих гидрофильные (например, простые полиэфирные) и гидрофобные (например, алкильные) доли. Агент для совместного загущения также повышает вязкость жидкости и требует применения очень малого количества агента для совместного загущения. Предпочтительные поверхностно-активные вещества представляют собой бетаины и четвертичные амины. Такие жидкости могут быть использованы для обработки нефтяных месторождений, например, при разрыве и заполнении скважинного фильтра гравием.
