Abstract

В способе обработки подземного пласта, содержащего песчаник, пробуренного стволом скважины, образуется суспензия жидкости-носителя, содержащая агент для модификации поверхности по крайней мере одного гидролизуемого кремнийорганического соединения, фосфонатного соединения или их комбинации. Данную суспензию вводят в ствол скважины под давлением на уровне или свыше давления гидроразрыва пласта. Вещество, растворяющее песчаник, вводят в ствол скважины одновременно или после введения суспензии. Агент для модификации поверхности может быть заключен в капсулу из герметизирующего вещества. Также обеспечивается композиция для применения в обработке подземных пластов, содержащих песчаник. Данная композиция включает водную жидкость-носитель, содержащую инкапсулированный агент для модификации поверхности по крайней мере одного из гидролизуемого кремнийорганического соединения и фосфонатного соединения, которое заключено в капсулу из герметизирующего вещества.
