Title
(RU) СОСТАВЫ И СПОСОБЫ
Abstract
(RU)

Составы для гидроразрыва пласта получают посредством смешивания понижающего трение гранулированного водорастворимого полимера с понижающим трение составом обратной полимерной эмульсии в присутствии органофильной глины, без необходимости специализированного промыслового оборудования. Состав можно дозированно вводить в воду с получением жидкости для гидроразрыва пласта, которая, как было обнаружено, является более технически выгодной и экономически эффективной.
