摘　　要：聚表二元体系的乳化性能有助于扩大波及体积,提高驱油效率,从而增加采收率,因此开展室内实验对复合体系乳化性能进行研究。结果表明:不同聚合物浓度的二元体系形成的乳状液,聚合物浓度越高,形成的乳状液更加稳定,破乳时间更长;不同浓度表面活性剂体系中,随着表面活性剂浓度的增大,形成的乳状液越稳定,破乳时间越长;二元体系乳状液黏度随水油比例的减小而增大,2 500万相对分子质量聚合物配制的二元体系复配效果优于3 500万聚合物配制的二元体系。The emulsifying performance of binary system is helpful to enlarge the swept volume,improve the oil displacement efficiency and increase oil recovery,experiments were carried out to study the emulsification performance of the composite system in lab.The results show that emulsion of binary system with different polymer concentration,the higher the concentration of polymer emulsion formed more stable,breaking time longer.Viscosity of binary system emulsion viscosity increases with the decrease of water oil ratio,and the compound effect of the two molecular weight polymer prepared by the 25 million system of is better than that of the polymer prepared by the 35 million polymer system.
