▎ 摘  要

NOVELTY - A composition useful for controlling fluid flow, comprises a quantity of fibers and a quantity of swellable particles comprising crosslinkable polymer chains and/or an assembling agent. USE - A composition useful for controlling fluid flow and for forming a gel formation in a target zone of subterranean environment (claimed). ADVANTAGE - The fibers improve the dispersion of the particles as compared to prior particle dispersions without added fibers and form a more complete plugging performance in vertically oriented fractures, fractures with abnormally high vertical aperture, or the other large openings, to prevent gravitational convection of the particles and poor swelling dynamics. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) method of forming a gel formation in a target zone of a subterranean environment, which involves introducing the composition into the subterranean environment; and (2) forming the composition which involves (i) dispersing the quantity of fibers in a carrier fluid and forming a homogeneous mixture; and (ii) dispersing the quantity of swellable particles in the homogeneous mixture, causing greater than or equal to 1 portion of the quantity of swellable particles to swell; or (i) mixing the quantity of fibers and the quantity of swellable particles to form a homogeneous mixture; and (ii) contacting the homogeneous mixture with a carrier fluid, causing greater than or equal to 1 portion of the quantity of swellable particles to swell. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the fiber-reinforced hydrogel.
