摘要：Plugging in fluid passageways of a subterranean hydrocarbon-bearingformation or associated production wells caused by the accumulation of insoluble saltprecipitates therein which results from an in situ interaction between precipitate

precursor ions in an injection water and resident ions already occurring in the formation isprevented by removing the precursor ions from the injection water by a reverse osmosismembrane before injecting the water into the formation.
