摘要： Improvements in the treatment of wells that penetrate subterranean formations are accomplished through the use of a polymer solution which includes a neutralized ionomeric polymer dissolved in an organic solvent and a polar cosolvent. The polymer has a backbone that is substantially soluble in the organic solvent and pendant ionomeric groups that are substantially insoluble in the organic solvent. The polar cosolvent solubilizes the pendant ionomeric groups such that the polymer solution upon introduction into the well has a viscosity less than about 20,000 centipoises and upon mixing with water the polar cosolvent is taken up by the water causing the polymer to aggregate and increase in viscosity sufficient to form a plug. The polymer solution may be used in well drilling operations, well completion operations, and secondary recovery operations.

摘要： This invention relates to a process for the formation of a neutralized sulfonated polymer having about 10 to about 60 meq. sulfonate groups, wherein the sulfonate groups are neutralized with a zinc counterion. A cement of a polymer having olefinic functional groups and a non-reactive solvent is contacted with a sulfonated agent such as an acyl sulfate. The sulfonated polymer is then neutralized with a solution of zinc acetate dissolved in a solvent system of methanol alone or methanol and water, wherein the volume percent of methanol based on non-reactive solvent is less than about 10. A carboxylic acid can be then added to the cement of the neutralized sulfonated polymer thereby forming a zinc salt of the carboxylic acid in situ, wherein the zinc salt of the carboxylic acid is a preferential plasticizer for the zinc sulfonate groups. The Brookfield viscosity at 0.6 rpm at room temperature of the cement of the zinc neutralized sulfonated polymer is less than about 50,000 cps.
