| 摘 要： | 本文建立了高温状态下表面活性剂在多孔介质中的运移方程。该方程考虑了活性剂的动态吸附，高温热降解，化学反应等因素。利用有限差分法将该方程与能量守恒方程进行了耦合求解。讨论了注入温度，注入速度，段塞尺寸等参数对活性剂运移的影响。结果表明这些参数对活性剂的运移及作用效果具有较大的影响。 |

| Abstract: | A model of surfactant transport in porous media at elevated temperature was developed. The model includes the effects of surfactant dynamic adsorption, thermal degradation and chemical reaction with mineral ions on surfactant transport was included in the presented model. By using finite difference method, the derived equation was solved coupling with energy conservation equations. The effects of temperature, displacement velocity and slug size on surfactant transport process were discussed. The results show that these factors play important roles in the process of surfactant transport. |
| Keywords: | surfactant adsorption thermal degradation temperature mathematical model |
