Production of a polyacrylamide solution used in an oil recovery process

摘要

A process for producing an aqueous partially hydrolyzed polyacrylamide solution employed to recover oil from a subterranean oil-bearing formation. The properties of viscosity and screen factor for an aqueous polymer solution are correlated to the polymerization reaction parameters. Values of the parameters are selected which correlate to the specific predetermined polymer properties capable of meeting the performance demands of the formation and the aqueous partially hydrolyzed polyacrylamide solution is produced at the selected values of the reaction parameters.
