摘要
在充分考虑聚合物溶液在地层中流动时发生吸附和弥散以及热降解作用的基础上 ,给出了浓度扩散—弥散数学模型 ,并针对低、中和高浓度聚合物溶液情况得出相应的Laplace空间分析解。利用该结果可以预测聚合物溶液浓度在地层中的分布变化 ,计算阻力系数 ,对于三次采油聚合物驱油藏动态监测具有较大的理论指导作用。
By considering the absorption,dispersion and the thermal degradat ion of the polymer fluid flowed in the formation,a mathematical model with polym er fluid diffusion and dispersion is developed.The solutions for the low,middle and high concentration polymer fluid is got in the Laplace space.The model can b e used to forecast the concentration distribution change of the polymer fluid in the formation,and to calculate the persistent coefficient.It's useful for the r eservoir dynamic monitoring in the third enhanced oil recovery.
