▎ 摘  要

NOVELTY - Fracturing fluid comprises an aqueous copolymer composition has an acrylamide-based copolymer, a graphene oxide (GO) additive, and a crosslinker comprises a metal. USE - Fracturing fluid used in hydraulic fracturing treatment. ADVANTAGE - The fracturing fluid reduces the friction pressure, and also has relative low viscosity, and the slick water treatment enables to carry 0.2-2 pound per gallon (ppg) of proppants and is also typically pumped at a higher pumping rate, e.g. 60-110 barrels per minutes (bpm). DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: A method of treating a subterranean formation, the method comprising: introducing a fracturing fluid into a subterranean formation, the fracturing fluid comprising: an aqueous copolymer composition comprising an acrylamide-based copolymer; a graphene oxide (GO) additive selected from a non-modified water-soluble graphene oxide and a bifacial hydrophilically-modified graphene oxide; and a crosslinker comprising a metal; and crosslinking the fracturing fluid in the subterranean formation to yield a crosslinked fracturing fluid. A method for reducing fluid friction during treatment of a subterranean formation, which involves: introducing a fracturing fluid into a subterranean formation, where fracturing fluid comprisesan aqueous copolymer composition comprising an acrylamide-based copolymer, a graphene oxide (GO) additive selected from a non-modified water-soluble graphene oxide and a bifacial hydrophilically-modified graphene oxide, and a crosslinker comprises a metal, and crosslinking the fracturing fluid in the subterranean formation to yield a crosslinked fracturing fluid.
