摘　　要：介绍了表面活性剂结构、三采用表面活性剂种类，并对表面活性剂驱油机理作了详细叙述。研究了三元复合驱的技术特点，指出选择合适的表面活性剂复合体系可在低表面活性剂浓度下，获得超低界面张力。This paper introduces the structure of the surfactant and the types of surfactants used in tertiary oil recovery, and the oil-driving principle of the surfactant is described. The technology characteristics of the Tribasic combined drive are studied. It is suggested that the super low interfacial tension can be obtained with a low concentration of the surfactants by selection of a proper combination system of surfactants.
