• An injection water viscosifier for enhanced oil recovery
  申请人：THE GOODYEAR TIRE & RUBBER COMPANY

  公开号：EP0094898A2

  公开（公告）日：1983-11-23

  High molecular weight N,N-dimethylacrylamide copolymers and terpolymers were synthesized. These polymers offer outstanding advantages as injection water viscosifiers in enhanced oil recovery processes including chemical, miscible, and steam or in processes requiring profile improvement through adsorption and/or gelation. They are very valuable in applications where high salinity is a problem since they are relatively insensitive to metal salts (such as those containing polyvalent ions, such as Ca++ and Mg++).

  合成了高分子量的 N,N-二甲基丙烯酰胺共聚物和三元共聚物。这些聚合物作为注水增粘剂在提高石油采收率工艺（包括化学、混溶和蒸汽）或需要通过吸附和/或凝胶化改善剖面的工艺中具有突出优势。这些聚合物对金属盐（如含有 Ca++ 和 Mg++ 等多价离子的金属盐）相对不敏感，因此在高盐度的应用中非常有价值。

  The invention provides monolayer films which not only have hydrophilicity and are excellent in such properties as antifogging properties, antifouling properties, antistatic properties and anti-condensation properties but also tend to exhibit excellent transparency even with a large film thickness and excellent scratch resistance, as well as stacks having the monolayer film. The monolayer film is obtained by preparing a mixture including a monomer composition and a solvent, the monomer composition including a specific monomer and a polyvalent monomer having two or more (meth)acryloyl groups and being free of sulfonic group, carboxyl group and phosphoric group in a specific molar ratio, the solvent having a specific solubility parameter σ; applying the mixture onto a substrate and removing at least part of the solvent; and polymerizing the monomer composition to produce a monolayer film having at least one anionic hydrophilic group selected from a sulfonic group, a carboxyl group and a phosphoric group and a specific anion concentration ratio (Sa/Da) of the anion concentration (Sa) at the outer surface to the anion concentration (Da) at the middle point between the inner surface in contact with the substrate and the outer surface.
