Abstract
The properties of a new hydrophobic associating polymer were evaluated in detail in this paper. The polymer enhances the effect of increasing viscosity for the assembling action of functional groups in molecular chain. Alkali and surfactant promote the association and result in the increasing of viscosity, so the concentration of polymer in ASP solution is less than that in solution without alkali and surfactant. The viscosity of polymer solution restored again when shear effect decreased or disappeared; the characteristic will make the polymer used in oilfield advantageously. The polymer has synergistic effect with surfactant, so the interfacial tension of oil and water was ultra-low in a wide range of chemical concentration; it is propitious to improve displacement efficiency. When the oil recovery is approximate, the amount of new hydrophobic associating polymer is 20% less than that of HPAM.
