研究了单一乳化剂辛基酚聚氧乙烯醚10（OP?10）及其复配体系对辽河油田稠油稳定性、流变性的影响，并研究了有机碱对复配体系界面张力的影响。结果表明，二元最佳复配方式为质量分数为1.0%的OP?10+质量分数为0.6%的油酸钠（YSN）；在最佳复配方式下，复配体系可使稠油形成稳定的乳状液，黏度从1 168.22 mPa·s降至57.57 mPa·s,降黏率为91.03%，分水率为21.33%；有机碱三乙醇胺（TEOA）可使复配体系界面张力降低至10-2 mN/m。

The effects of a single emulsifier octylphenol ethoxylate 10 (OP?10) and its compounding system on emulsion stability, rheology and the effect of organic bases on the interfacial tension were investigated. The results show that the optimal binary composition is as follows: The mass fraction of OP?10 is 1% and the mass fraction of sodium oleate (YSN) is 0.6%.The optimum compounding method can produce stable emulsion with thick oil, and the viscosity can be reduced from 1 168.22 mPa?s to 57.57 mPa?s, with the viscosity reduction rate of 91.03% and the water separation rate of 21.33%. The organobase triethanolamine (TEOA) can reduce the interfacial tension of the compounded system to the 10-2 mN/m level.
