THERMALLY STABLE POLYMERIC SCALE INHIBITOR COMPOSITIONS

摘要

The present invention relates to a thermally stable polymeric scale inhibitor compositions having a pH of from 5 to 10, and use thereof. Preferably, the polymeric scale inhibitor is a polycarboxylic acid (co)polymer not containing a sulfuric acid group and/or sulfonate group. The polymeric scale inhibitor compositions of the present invention are particularly suitable for high pressure/high temperature scale inhibition treatment of oil and gas production wells and/or subterranean formations.
