Abstract

Прямая эмульсия скважинного флюида включает немасляную дисперсионную среду, маслянистую дисперсную фазу, стабилизирующий агент, маслосмешиваемую смолу на эпоксидной основе и отверждающий агент, где скважинный флюид представляет собой устойчивую эмульсию, имеющую вязкость больше чем 200 сП. В некоторых воплощениях отверждающий агент является маслосмешиваемым отверждающим агентом, в других воплощениях отверждающий агент является маслонесмешиваемым отверждающим агентом.
