As pollutant migrated into the capillary zone,capillary tension restricted the vertical movement.The pollutant must overcome the entrapment pressure of oil-water interface before entering the capillary zone, and pollutant accumulated on the top of the capillary zone to become pressurized.The pore pressure of pollutant exceeded the entrapment pressure of oil-water interface,and pollutant entered the capillary zone and formed a lens above the groundwater level.

当污染物迁移到地下毛细管区后，其向下的运动将整体受到毛细张力的阻碍，污染物要想进入毛细饱和带必须克服油-水界面的进气压力，这时污染物在毛细饱和带顶部聚集以期获取压力，同时将产生以水平方向为主的迁移，最终随着污染物的压力超过其进气压力，导致污染物进入毛细饱和带，在地下水水位上形成一个透镜体。
