Abstract: A mathematic model of surfactant loss in one dimension for flow state (see Equation (5) or (7)),has been derived from theory of mass transfer.It was presented that the equation was resolved with the differential method.This model was examined with the changing of the length column packed Laojunmiao reservoir sand as well as the changing of flow volume injected flooding solution.Experiments showed that under above conditions prediction from the model were of good agreement with the experimental data.

Key words: enhanced oil recovery, surfactant, loss, mathematical model

摘要： 从传质理论出发,推导出了表面活性剂损耗的一维动态数学模型,并提出用差分法求解方程.通过改变柱长和注入体积流量对所建立的模型进行了实验验证.结果表明,在上述情况下,模型计算值和实验值的相符性是良好的.
