Abstract

Способ разобщения текучих материалов в отношении подземной скважины может включать в себя отделение текучего цемента от флюида с помощью помещения текучего изолирующего вещества между цементом и флюидом, причем изолирующее вещество, по существу, предотвращает вытеснение цемента под действием силы тяжести через изолирующее вещество и во флюид. Другой способ разобщения текучих материалов может включать поступление изолирующего вещества в ствол скважины над флюидом, уже находящимся в стволе скважины, и после этого поступление цемента в ствол скважины над изолирующим веществом. Система для использования в связи с подземной скважиной может включать текучий цемент, изолированный от первого флюида текучим изолирующим веществом, помещенным между цементом и первым флюидом, в результате чего изолирующее вещество, по существу, предотвращает вытеснение цемента под действием силы тяжести через изолирующее вещество и во флюид.
