摘要

"Method for reducing friction resulting from turbulent flow in an aqueous fracturing fluid in an oilfield fracturing process." a method for reducing friction resulting from turbulent flow in an aqueous fracturing fluid in an oilfield fracturing process, comprising adding to the aqueous fracturing fluid an effective friction reducing amount of one or more dispersion polymers, wherein the polymer The dispersion compound is comprised of about 5 to about 95 mole percent of one or more nonionic monomers and about 95 to about 5 mole percent of one or more cationic or anionic monomers, and has a molecular weight of at least minus 100,000.
