摘　　要：介绍由天然油脂下脚料制成的天然混合羧酸盐的性能,重点叙述了它作为表面活性剂与碱和聚合物组成三元复合驱油体系,在三次采油时,对不同酸值和不同水质的原油,采用不同配方的驱油体系和现场试验增产原油的情况,同时介绍了天然混合羧酸盐可以降低高稠油粘度,用于稠油的开采。The properties of the natural mixed carboxylates (SDC) prepared from the heels ofoils and fats were presented, and the trinary flooding system composed of SDC surfactant, alkali andpolymer was described. Varied formulations of flooding system were applied for the crude oils havingdifferent acid number and different water quality to enhance oil recovery. The extensive applications ofSDC on viscosity reducing and exploiting of viscous crude oils were also introduced.
