Enhancing gel strength |
摘要 |
A composition adapted to form a strengthened gel for treating subterranean formations is described, the composition comprising an aqueous liquid containing an effective amount of a water soluble crosslinkable polymeric gel forming material and a crosslinking agent in an amount sufficient to crosslink said material, and a gel strengthening amount of an inert colloidal particulate material. A method for forming a strengthened gel in at least a portion of a subterranean formation is also disclosed, the method comprising injecting into at least a portion of a formation an aqueous liquid gel forming composition of the type described, and allowing the aqueous liquid composition to form a strengthened gel.
