УСТРОЙСТВО И СПОСОБ ДЛЯ ГИДРАТАЦИИ ГЕЛЯ, ПРЕДНАЗНАЧЕННОГО ДЛЯ ИСПОЛЬЗОВАНИЯ В ПОДЗЕМНОЙ СКВАЖИНЕ

摘要

The present invention relates to a method and system for hydrating a gel for treating a wellbore penetrating a subterranean formation. The method includes directing a base fluid through an inlet into a mixer having an inner chamber housing a plurality of impellors extending radially from and rotating about a hub, causing a centrifugal motion of the base fluid, feeding a quantity of gel into the mixer, mixing the gel with the base fluid and discharging the now-hydrated gel from the inner chamber through an outlet of the mixer. A prewetting device may also be used. Thereafter, a variety of additives may be added to the gel fluid mix to form a fluid treatment to be introduced into a subterranean formation.
