摘要
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 introduced and compared each other,and further a more complete and reasonable model is developed and analyzed.
