Abstract

В настоящем изобретении предлагается скважинный флюид на основе углеводородов в форме эмульсии, включающий непрерывную фазу, включающую масло, и дисперигованные в ней первую жидкую фазу и вторую отдельную жидкую фазу, при этом первая диспергированная жидкая фаза представляет собой солевую фазу, а вторая диспергированная жидкая фаза включает полярную органическую жидкость, при этом указанная полярная органическая жидкость не растворяется или практически не растворяется в солевом растворе, включающем указанную первую диспергированную жидкую фазу, но растворяется в чистой воде. В настоящем изобретении предлагается также способ эксплуатации скважины, который включает следующие стадии: (а) введение в скважину скважинного флюида по настоящему изобретению, (б) образование глинистой корки и (в) контактирование дополнительного количества флюида с глинистой коркой, причем уровень минерализации указанного дополнительного флюида ниже по сравнению с уровнем минерализации указанной первой диспергированной жидкой фазы и в указанном дополнительном флюиде растворяется указанная полярная органическая жидкость. Флюид по настоящему изобретению можно использовать при различных бурильных работах, при которых сначала требуется низкая проницаемость глинистой корки, а на последующих стадиях необходима ее высокая проницаемость.
