摘要: 根据表面活性剂在油层中损失实验数据的回归分析,得到表征有极值损失的经验公式:SD=CDaca(1-CD)。采用解析差分格式,对一维化学驱输运方程进行了数值模拟。给出了单向和径向浓度分布曲线和表面活性剂损失曲线。其结果可用来预估表面活性剂在油层中的渗流损失。

Abstract: This paper presents a formula characterizing surfactant loss in reservoir rock with a maximum value by a regression analysis of experimental data. Numerical simulation of surfactant loss in chemical flooding can be used to predict the surfactant loss in reservoir.
