Abstract

Кислотную вязкоупругую жидкую композицию составляют с кислотой, например хлористо-водородной кислотой, катионогенным поверхностно-активным веществом, например четвертичным амином, и солью, обеспечивающей разрушение, например NHCl. Жидкая композиция имеет низкую вязкость при составлении, подвергается увеличению вязкости по мере потребления кислоты при взаимодействии с кислотно-реакционноспособным веществом и возвращается к приблизительно начальной вязкости по мере потребления последней части кислоты. Жидкая композиция применяется в качестве закупоривающей жидкости или в качестве основной обрабатывающей жидкости при нефтепромысловых обработках, таких как структурная кислотная обработка и кислотный разрыв.
