The invention provides a method for improving super-heavy oil steam flooding recovery efficiency. The method for improving the super-heavy oil steam flooding recovery efficiency comprises the steps that a certain amount of steam or tracer agent is injected through an injection well; when thermal recovery blockage regulation is determined to be carried out on a producing well according to the occurrence time and direction of the steam or the tracer agent, overall blockage regulation of a steam flooding well set is carried out; a certain amount of nano-catalyst is injected before the injection of the steam or along with the steam; the well is shut in and production is carried out in a limited mode after well shut. The method for improving the super-heavy oil steam flooding recovery efficiency can effectively reduce the viscosity of super-heavy oil in an oil reservoir, improve the flowing capacity of the super-heavy oil in the oil reservoir, and effectively drive crude oil to the production well around the steam injection well.
