摘要：以双酚 AF（BPAF）、对羟基苯磺酸（PHSA）、聚氧乙烯辛基苯酚醚-10（OP-10）为原料制得乳化降黏剂
AFOP-10（阴-非离子型乳化降黏剂），测试了 AFOP-10 的表面性质和耐温耐盐性能，考察了该降黏剂结构与性
能的关系，初步探究了该降黏剂的降黏机理。研究结果表明：乳化降黏剂 AFOP-10 的 HLB 值为 11.37，浊点（T k ）
为 75 ℃，临界胶束浓度（CMC）为 0.08 g/L，AFOP-10 的表面张力 γ CMC =30.30 mN/m，具有较好的表面活性。
该降黏剂热降解温度高达 363 ℃，单体配比 n（BPAF）∶n（PHSA）∶n（OP-10）=1∶6∶9 时，降黏剂最高
可耐盐浓度为 49476 mg/L，用矿化度为 8246 mg/L 的盐水配制的质量分数 1.0%的 AFOP-10 溶液经 300 ℃老化
处理 24 h 后，AFOP-10 仍具有良好的活性，降黏率可达 98.50%以上。AFOP-10 对渤海油田不同油区的油品都
有较好的乳化降黏效果，具有良好的普适性。

Abstract: An anionic-nonionic emulsified viscosity reducer, AFOP-10 was synthesized from bisphenol AF
(BPAF), p-hydroxybenzenesulfonic acid (PHSA), and octyl phenol polyoxyethylene ether-10 (OP-10). Its
surface properties, temperature resistance and salt tolerance were tested. The structure-function relationship
of AFOP-10 was investigated. The mechanism of the emulsified viscosity reducer was preliminarily
explored. The results showed that the HLB value, turbidity point (T k), critical micelle concentration (CMC),
and surface tension (γ CMC) of AFOP-10 were 11.37, 75 ℃, 0.08 g/L, and 30.30 mN/m, respectively.
AFOP-10 exhibited good surface activity. The thermal degradation temperature of AFOP-10 was 363 ℃.
The maximum salt tolerant concentration of the prepared emulsified viscosity reducer with a molar ratio of
BPAF, PHSA and OP-10 of 1∶6∶9 was 49476 mg/L. A solution with a mass fraction of 1.0% AFOP-10
was prepared containing a salinity of 8246 mg/L. AFOP-10 still had excellent activity after the solution was
treated at 300 ℃ for 24 h, with a viscosity reduction rate of over 98.50%. AFOP-10 has good emulsification
and viscosity reduction effect on oil products in different areas of Bohai Oilfield, and shows good
universality.
Key words: emulsified viscosity reducer; temperature resistance and salt tolerance; structure-function
relationship; bisphenol AF; mechanism of viscosity reduction; oil field chemicals
