泡沫剂可以减缓气驱中的气窜和重力超覆现象。随着泡沫剂在三次采油中的广泛应用,出现了许多泡沫驱的数值模拟方法。本文介绍并对比了各种模拟方法(半经验关系式模型、总量平衡模型、临界毛管力模型、阻力系数模型、组分方法、渗滤和网络模型以及半总量平衡模型等) ,同时指出了发展更完善和合理的模型所要做的进一步工作。

Foam can retard gas channeling and gravity override in gas flooding. As foam was widely used in EOR process , various methods of numerical simulation of foam flow in porous media appeared ,including empirical mobility modification , population balance model , limiting capillary pressure model , resistance factor model , compositional method , percolation and network model ,and bubble population correlation approach. All these models are int roduced and compared each other, and further a more complete and reasonable model is developed and analyzed.
