Abstract: Diethanolamine and maleic anhydride were used to synthesize hyperbranched unsaturated poly
(amide-ester) (HP). Then, HP reacted with succinic acid monolauramide sulfonic acid to prepare
anionic-nonionic hyperbranched surfactant HPSA. The structure of HPSA was characterized by FTIR,
1
HNMR and GPC. The critical micelle concentration (CMC), surface/interfacial tension (SFT/IFT), wetting
properties, anti-aging properties under high temperature and high salt, emulsifying property and oil
displacement efficiency of HPSA were measured. The results showed that HPSA had a CMC of 0.162 g/L,
good surface/interfacial activity (γ CMC=25.1 mN/m, δ CMC=0.077 mN/m). Under high temperature (150 ℃)
5
and high salt〔ρ(NaCl)=2×10 mg/L〕, the surface tension was about 25 mN/m after aging 15 days. Besides,
HPSA showed good wetting properties and wetting reversal properties. Moreover, the emulsification
performance of HPSA was comparable with sodium dodecyl sulfonate, but its emulsification performance

under high salt (ρ(NaCl)=8×10 mg/L, ρ(CaCl 2)= 1×10 mg/L) was better than that of sodium dodecyl
sulfonate. The core flow test indicated that 0.3 g/LHPSA improved the enhance oil recovery (EOR) about
5.3% on the basis of water flooding when the injection volume was 0.5 PV. HPSA was suitable to high
temperature and high salinity oil field as a new oil-displacing agent.
