Abstract

Abstract:

The rheology of hydrophobic associating polymer/surfactant solution system and the interfacial tension between the system and simulation oil have been studied in this paper. Experimental results show that there are obvious interactions between hydrophobic associating polymer ( NAPs) and surfactant
(SDBs), and synergistic effects exist in some conditions. Maximum viscosity of the NAPs/SDBS system has got at certain surfactant concentration. The interaction of NAPs/SDBS has made the surfactant concentration shifts right at which the minimum interfacial tension between polymer/surfactant and simulation oil obtained, and increases the interfacial tension.

Key words: hydrophobic associating polymer, surfactant, rheology, interfacial tension, enhanced oil recovery
