在两维纵向非均质正韵律物理模型上开展了牺牲剂对大庆油田三元复合驱油效果影响的物理模拟研究；探讨了牺牲剂六偏磷酸钠、聚磷酸钠和木质素磺酸盐在不同注入方式下对三元复合驱油效果的影响。物理模拟研究表明，六偏磷酸钠价格低、货源广，可成为现场应用的牺牲剂；三元复合体系注入之前，注入少量牺牲剂六偏磷酸钠，可使三元复合驱采收率进一步提高３０％；用等量的牺牲剂代替部分表面活性剂在三元复合体系注入之前注入，对三元复合驱油效果影响很小，但可大大降低三元复合驱成本。该研究成果对大庆油田大面积推广三元复合驱具有指导意义
Physical simulation of the effect of sacrificial agent on ASP flooding in Daqing oilfield was carried out on a two-dimensional longitudinal heterogeneity positive-rhythmic physical model. The effects of sacrificial agent sodium hexametaphosphate, sodium polyphosphate and lignin sulfonate on Effect of Different Injection Methods on the Effect of ASP Flooding. Physical simulation studies show that sodium hexametaphosphate is low in price and widely available as a sacrificial agent for on-site application. Before injection of the ternary composite system, a small amount of sodium hexametaphosphate, a sacrificial reagent, can be injected to further increase the oil recovery of the ASP flooding 3 0%; with the same amount of sacrificial agent instead of part of the surfactant injected into the ternary composite system, the impact of ASP flooding little effect, but can greatly reduce the cost of ASP flooding. The results of this research have great guiding significance for the large-scale popularization of ASP flooding in Daqing Oilfield
