Abstract

Abstract:

A novel copolymer was synthesized using acrylamide，acrylic acid，N–allylimidazole and N，N–diallyl oleamide.
The optimal conditions for synthesis such as temperature，pH，initiator and monomer loadings were studied. The viscosity
measurements，and rheological measurement of the obtained copolymer were characterized by Infrared（IR）spectroscopy，H
nuclear magnetic resonance spectrometer（1H NMR），scanning electron microscope（SEM）. X-ray diffractometer（XRD）were
also conducted to investigate the clay stabilization property of the obtained copolymer. The results indicated that the copolymer
was of good temperature tolerance，and anti-shear abilities and salt resistance. Core flooding result revealed that the enhanced
oil recovery could be up to 13.8%. The result of X-ray diffractometer revealed a good clay stablility of sodium montmorillonite.

Key words: enhanced oil recovery, polyacrylamide, imidazoline ring, EOR chemical, crystalline interspace
