摘要： The method involves introducing the polymer into oil stores. The water-soluble polymer is used in the form of a dispersion of the water-soluble polymer as well as at least one water-soluble polymer stabilizer. The viscosity of the dispersion in the neutral and basic pH region is higher than in the acidic region.
