文摘The effects of oleic acid concentrations, neutralization ratio, added salts and partially hydrolyzed polyacrylamide(HPAM) on the transient interfacial tension between oleic acid-sodium oleate Anxed aqueous solution and crude oil were studied by spinning drop method. The results indicated that the equilibrium tdrie of interfacial tension decrease as the concentrations of surfactant increase. When polymer was added to the aqueous solution the equilibrium time became longer. The effect of NaCl concentration was relatively complicated. At the optimum salinity the time effect was the shortest.
