The present disclosure provides a method of nano-armored foam reinforced geological storage of carbon dioxide. A pre-COslug, a surfactant foam slug, a nanoparticle-enhanced foaming liquid slug and a post-COslug are injected successively into a geological storage formation, where the post-COslug is injected multiple times in equal portions, and a well soaking is performed after each injection. A nanoparticle-enhanced foaming liquid is made by using nanoparticles of different dimensions or using nanoparticles of multiple dimensions at the same time based on the reservoir characteristics. During the process of well soaking, a supercritical COand the nanoparticle-enhanced foaming liquid in the formation can in situ generate single-dimensional or composite-dimensional nano-armor reinforced COfoam underground, which can plug channeling path and expand the COstorage range, and make respective slugs cooperate with each other, thereby enlarging a geological storage amount of CO.
