Abstract

Описаны способы и композиции для контролируемого добавления компонентов, снижающих вязкость вязкоупругих жидкостей на основе поверхностно-активных веществ, или для контролируемого изменения концентрации электролита или состава вязкоупругих жидкостей на основе ПАВ. Один из аспектов данного изобретения относится к применению внутренних агентов для понижения вязкости с замедленным активированием. Другой аспект данного изобретения относится к применению предшественников, высвобождающих расщепляющую систему, например спирт, в результате таких процессов, как плавление, медленное растворение, взаимодействие с соединением, присутствующим в жидкости или добавляемым в жидкость во время или после стадии инжектирования, разрыв капсулирующего покрытия и деадсорбция понижающего вязкость агента, абсорбированного в твердых частицах. В соответствии со следующим аспектом данного изобретения спирты включают в подушку для снижения вязкости при низком уровне сдвига, а также для снижения сопротивления потока жидкостей для обработки во время желаемой фазы обработки.Международная заявка была опубликована вместе с отчетом о международном поиске.
