改变三元复合体系和油的组成，考察了影响体系界面张力的因素，分析了三元复合体系与脱气原油和模拟油间界面性质差异的原因，探讨了三元复合体系改性的途径和效果. 研究结果表明，用污水复配的三元复合体系能够与大庆脱气原油形成超低界面张力，但与模拟油间的界面张力稍差，这是由于二者化学组成差异所致；在三元复合体系中，增加碱和活性剂的质量浓度，它与脱气原油或模拟油间的界面张力降低；加入交联剂后，阻力因数和残余阻力因数增加，但界面张力略为增大；聚合物的质量浓度对界面张力影响不大.

In order to analyze the factors that affect tension property of system between alkaline-surfactant-polymer (ASP) and Daqing oil, laboratory evaluations have been made, and interesting results are obtained. Besides what has been mentioned above, the methods of improving ASP properties on resistance factor had also been studied by addition of cross-link agent in the ASP system. The experimental results show that the oil compositions will affect the tension property, and artificial oil compositions are similar to crude oil in reservoir. These conclusions are beneficial to ASP flooding in Daqing Oil Field.
