Abstract

Способ уменьшения водного содержимого буровой жидкости на нефтяной основе включает контактирование обратно-эмульсионной скважинной жидкости с водопоглощающим полимером, взаимодействие водопоглощающего полимера с буровой жидкостью в течение периода времени, достаточного для того, чтобы водопоглощающий полимер поглотил по меньшей мере часть водосодержащей жидкости из скважинной жидкости, и извлечение водопоглощающего полимера, содержащего абсорбированную воду, из скважинной жидкости.
