Method of making well treatment gel.

摘要

A method of making a well treatment fluid, such as a fracturing gel or the like, in which dry polymer is fed into a metering feeder (16) which accurately meters the rate of polymer fed into a water spraying mixer (38). A vent (40) is preferably provided so that air can enter with the polymer as necessary. Water, with or without a buffering compound therein, is flowed through a water inlet (114) of the mixer. The water is preferably jetted into a spiraling flow pattern through which the polymer falls and is substantially wetted. Auxiliary water inlets may be used to add additional water to the water-polymer slurry to increase mixing energy and increase the amount of slurry produced. The slurry is discharged into a mixing tank (54) with an agitator (56) and then into a holding tank (64). The slurry may also pass through a shear device to further increase the rate of viscosification of the slurry. In this way, the slurry may be continuously mixed on a real time basis while carrying out the well treatment operation, such as the fracturing of a formation.
