    摘要: A method of recovering oil from a subterranean oil-bearing reservoir uses an injection fluid comprising a viscosifying polymer in a low salinity water. The reservoir is penetrated by one or more injection wells and by one or more production wells. The method comprises injecting the injection fluid into at least one of the injection wells in a slug size in the range of 0.4 to 1.5 pore volumes (PV).
