Abstract

Композиция для обработки скважин образована из водного раствора сшиваемого способного гидратироваться полимера. Комбинация раствора полимера с твердой борной кислотой или боратным сшивающим агентом и буферным агентом для регулировки рН на основе твердого оксида или гидроксида металла, который имеет ограниченную растворимость (менее 100 кг/мпри 20°С) в растворе полимера, дает раствор с рН от около 8 до около 11. Композиция может быть введена в подземный пласт через скважину, проходящую через пласт. Композиция может обеспечить по меньшей мере одно сокращенное время восстановления вязкости после сдвига и увеличение термической стабильности водного раствора полимера.
