Abstract

Представлены композиции и способы для замедленного разрушения (разжижения) гелей вязкоупругих поверхностно-активных веществ внутри пор пласта, в частности, для использования в гидравлическом разрыве пласта. Разжижение внутри пор пласта выполняется без механического вмешательства или использования второй жидкости. Используются окисляющие агенты, такие как воздух, кислород, персульфаты, броматы, пероксиды и другие. Разжижение может быть ускорено, например, частицами, способствующими росту свободных радикалов, или замедлено, например, поглотителем кислорода. В некоторых соляных растворах, например бромидных растворах, некоторые цвиттерионные вязкоупругие жидкостные системы, которые могут декарбоксилировать и которые требуют анионсодержащего совместного поверхностно-активного вещества, подвергаются замедленному разрушению, если присутствует кислород, например от получения жидкости или в пене.
