摘　　要：应用光学显微镜确定了大庆油田三元复合体系是一种分散体系 ,表面活性剂以分子聚集体的形式分散在体系中。二元体系的粘度随表面活性剂浓度的增加而增大。该表面活性剂的cmc范围为0 04%～0 06 % ,在三元情况下 ,平衡后水相中表面活性剂浓度不大于0 063 %。二元体系与油乳化平衡后 ,水相中表面活性剂浓度在0 08 %以下。大部分表面活性剂以乳化状态存在于油水相之间。s:The three combination flooding system in Daqing oil field was determined as a kind of dispersion by microscope technique.The surfactant can form aggregate in aqueous solution.The viscosity of surfactant/alkali system increased with the increment of ORS concentrations.The ranges of its cmc are 0.04～0.06%.In conditions of the three components,the ORS concentration is no more than 0.063% after its equilibrium.The ORS concentration is below 0.08% when the emulsified system of kerosene and surfactant/alkali solution reached a state of equilibrium.The most of surfactant is exist between oil and water phases.
