摘　　要：选用大庆炼化相对分子质量为1900×10^4，浓度为1500mg／L的聚合物溶液，与SS（石油磺酸盐）无碱二元体系；与SS、碳酸钠三元体系。二元体系和三元体系均能达到超低界面张力。对单聚体、二元体和三元体进行了黏弹性、黏度及驱油试验。研究表明，三元体系在表活剂浓度为0．3％、碱浓度为1．2％时，界面张力达到3～10mN／m，二元体系表活剂浓度为0．3％时也能达到3～10mN／m；由于没有碱的加入，单聚的黏弹特性要高于复合体系，在复合体系中，二元体系的黏弹特性高于三元体系。人造非均质驱油实验结果得出，SS无碱二元体系的采收率达到了30．1％，比单聚高出6．7％，比三元复合体系高出2．7％。To select Daqing Refining and Chemical relative molecular mass of 1 900 × 10^4, the concentration of polyer solution of 1 500 mg/L, it and SS（ petralum sulfonate）are composed of two components system it and SS, sodium carboate are composed of three components system. Two and three components system can achieve ultra--lour in terfacial tension. The viscoelastie properties, viscosty and Y displacement experiment of the monomer, two and three components system were conduclid. Research shows that, three element in the surfactant concentration is 0. 3% ,the alkali concentration is 1.2% ,the interfacial tension can reach 10-3 mN/m,two yuan of surfactant concen- tration of 0.3% can reach 10 -3 mN/m;because of absence of alkali ,the viscoelastic properties of monomers was higher than - that of the composite system, in the composite system, elastic properties two system to more three yuan system. Artificial heterogeneous oil displacement experiment results, SS alkali two yuan system recovery rate reached 30.1% ,6.7% higher than the single poly,2.7% higher than the three element composite system.
