摘要： A process for altering the permeability of a subterranean formation comprises injecting into the subterranean formation a gelling composition which comprises a carboxylate-containing polymer, a crosslinking agent, and a liquid such as a produced brine wherein the polymer forms a gel in the formation, in the presence of the crosslinking agent. The polymer can have a molecular weight of from about 10,000 to about 30,000,000, contain about 0.01 to about 10 mole % of a carboxylate group, and be present in the gelling composition in the range of from about 100 to about 100,000 mg per liter of the composition.

摘要： A gelling composition comprises a multivalent metal compound-crosslinkable polymer such as a carboxylate-containing polymer, a multivalent metal compound such as a zirconium compound, a liquid, and a pH-lowering agent such as carbon dioxide wherein the composition is prepared by combining the polymer and multivalent metal compound to form a mixture and, thereafter, introducing carbon dioxide to the mixture. A process for treating a subterranean formation can comprise the steps of: (1) combining a polymer with a multivalent compound to form a mixture; (2) introducing the another mixture into a subterranean formation; and (3) introducing carbon dioxide into the mixture.

摘要： In the adhesion of metallic materials to polymers, new adhesive agents of nitrogen containing hetrocyclic polymers such as compositions of imidazole-pyrridine, pyrrolidone-pyridine, and imidazole-pyrrolidone solutions have been discovered as useful. These agents also exhibit anti-corrosion effects. Adhesion and/or reduction of anti-corrosion can be accomplished by pre-coating the metal material with at least one of these agents prior to applying the polymer, or by preblending the polymer with at least one of these agents followed by applying the blend to the metal, under suitable conditions.
