Due to high injectivity，various injection mode and low cost，foam system had been paid more and more attention on the application of profile control in low permeability oilfield. However，foams were vulnerable to high temperature，high salt，high pressure and other environmental impacts in the practical application，which could reduce the foam stability. The current research progress and application of nanoparticle stabilized foam system was summarized in this paper，and the mechanism of nanoparticle in stabilizing foam was analyzed. It was suggested that a integrated foaming and stabilizing agent could be obtained by changing the surface property of nanoparticle. This kind of integrated foaming and stabilizing system，with high stability and mechanical strength，and generating in formation，would have an important influence on foam profile control technology in low permeability oilfield.
