摘　　要：为了尽量降低产品成本,研究了助排剂YMZP-2的四种调配成分——全氟壬烯氧基苯磺酸钠(OBS)、辛烷基苯酚聚氧乙烯醚-10(OP-10)、氯化钙、甲醇对表(界)面张力的影响,在此基础上通过正交试验对助排剂的配方进行了优化得到了新助排剂YMZP-3,考察了该助排剂的表界面性能。研究结果表明:OBS是影响表面张力的主要因素,OP-10是影响界面张力的主要因素。OBS和OP-10在水溶液中具有很好的协同效应,浓度100 mg/L的OBS溶液和OP-10溶液的表面张力分别为27.4和32.9 m N/m,与煤油间的界面张力分别为5.6和5.1 m N/m,浓度均为50 mg/L的OBS和OP-10的复配体系的表面张力为21.4 m N/m,与煤油间的界面张力为2.3 m N/m。组成为OBS 1.2%、OP-10 1.2%、氯化钙1.8%、甲醇25%的YMZP-3可以满足助排剂表(界)面张力指标要求,成本较YMZP-2降低40%左右。In order to reduce the product cost as much as possible, the effect of the agent, s four ingredients--perfluorononyl alkenyloxy benzene sulfonate （OBS）, octyl phenol polyoxyethylene ether-10（OP-10）, calcium chloride, methyl alcohol, on the surface （interfacial） tension of the clean-up additive YMZP-2 was researched, on this basis, the formulation of clean-up additive was optimized by orthogonal experiment, a new clean-up additive YMZP-3 was obtained, and the properties of YMZP-3 Investigated was investigated. The experimental results showed that, OBS was the dominant factor to affect the surface tension, while OP-10 was the dominant factor to affect the interracial tension. OBS and OP-10 had a good synergistic effect in the water solution. When the OBS and OP-10 concentration was 100 mg/L, respectively, the surface tension was 27.4 and 32.9 mN/m, respectively; and the interracial tension between the OBS solution （OP-10 solution） and the kerosene was 5.6 （5.1） mN/m. However, the surface tension of the complex system, composed of 50 mg/L OBS and 50 mg/L OP-10, was only 21.4 mN/m, and the interracial tension between the complex system and the kerosene was only 2.3 mN/m. The optimal recipe of clean-up additive YMZP-3 was as follows, 1.2% OBS, 1.2% OP-10, 1.8% calcium chloride and 25% methyl alcohol, which could meet the requirements of the indexes of the superficial （interfacial） tension, and the cost of the YMZP-3 was lower than that of YMZP-2 by 40%.
