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.A method for reducing the aqueous content of an oil-based drilling fluid includes contacting a reverse emulsion wellbore fluid with a water-absorbent polymer, contacting the water-absorbent polymer with the drilling fluid for a period of time sufficient for the water-absorbent polymer to absorb at least a portion of the aqueous fluid from the wellbore fluid, and recovering a water-absorbent polymer containing absorbed water from the wellbore fluid.
