“…Te synergistic efect of polymer-surfactant mixtures plays an important role in the enhanced oil recovery (EOR) [1][2][3][4][5]. Because the polymer can improve the viscosity of displacing fuid and increase the sweep efciency, the surfactant can decrease the interfacial tension and enhance the oil washing efciency of displacement media [6][7][8].…”

A dendrimer amphiphilic polymer (A-D-HPAM) was synthesized by aqueous solution polymerization of acrylic acid (AA), acrylamide (AM), 2-acrylamido-2-methyl-1-propane sulfonic acid (AMPS), hydrophobic monomer of cetyl dimethyl allyl ammonium chloride (DMCAAC-16), and skeleton monomer of GA1.0, using ammonium persulfate and sodium bisulfite as initiators. The chemical structure of A-D-HPAM was, respectively, analyzed by Fourier transform infrared spectrometer (FTIR), nuclear magnetic resonance (NMR) spectroscopy, and scanning electron microscope (SEM). The tackifying property, the resistance of shear, temperature and salt, the interfacial tension, and the oil displacement performance of A-D-HPAM were determined. Compared with solutions of HPAM (hydrolyzed polyacrylamide) and HPAM-SDBS (sodium dodecyl benzene sulfonate), A-D-PAM exhibits the optimal properties, especially achieving the enhanced oil recovery (EOR) of 15.1%.
