Thirdly According to macroscopic physical simulation the subject district the effect that profile control effect sweeping oil effect and gas up-flowing effect have on ultimate oil displacement efficiency at the aspect of oil recovery efficiency .

Particularly profile control sweeping oil and gas up-flowing effect devotes to oil displacement efficiency during foaming oil displacement and if designs the simulation model of microscopic according to experiments .
