Therefore the chapter gives out a method to enhance the oil recovery ------surfactant flooding, choosing firstly non hydronium surfactant compound system that is due to oil permeable bed of Xing-shugang oil field, and measuring relative permeability in surfactant flooding, surfactant flooding has the purpose to reduce oil-water interface intension and add oil disperse in water.

为此本文提出了注活性水提高低渗透油层开发效果的技术方法，优选出适合杏树岗油田低渗透油层条件下的非离子表活剂复配体系，并对活性水驱油时的相对渗透率进行了测定，活性水驱油可以起到降低油水界面张力、增加原油在水中分散的目的。
