The influence of temperature, gas-liquid ratio, gas-liquid rate, residual oil saturation and permeability on steam foam sealing ability is studied on the basis of microscopic percolation study.
A natural escape of hot fluids from the steam reservoir should be prevented by cap rocks with low permeability.
只要存在通透性能低的盖层，蒸气储放热流体就不会自行外逸。

The model simulates sodium flow in the steam generator as quasi-continuum. The model USES volume porosity, area permeability and distributed resistance to model the tubes and support plates.
