The invention discloses a profile control oil-displacement agent for a core-shell type inorganic / organic polymer composite microballoon. A preparation method of the core-shell type inorganic / organic polymer composite microballoon comprises the following steps of carrying out surface modification of inorganic cores of inorganic nano-particles such as silica particles and magnetic particles, and carrying out graft polymerisation by a dispersion polymerization method or an inverse emulsion polymerization method to form polymer shells (such as polyacrylamide cross-linked copolymers) on the surfaces of the inorganic cores. The inorganic components and the organic components bind by chemical bonds so that the core-shell type inorganic / organic polymer composite microballoon has very stale structure. The core-shell type inorganic / organic polymer composite microballoon retains the advantages of polymer microballoons and inorganic particles, and has strong heat-resistant and mineralization-resistant capabilities, high plugging strength and good dilatancy. The core-shell type inorganic / organic polymer composite microballoon can move in rock pores and can plug the rock pores. When a plugging pressure difference is improved to a certain degree, elastic deformation of the core-shell type inorganic / organic polymer composite microballoon can be produced and the deformed core-shell type inorganic / organic polymer composite microballoon sequentially moves to a deep rock stratum part so that a liquid flow direction is changed gradually and a crude oil yield is improved. The profile control oil-displacement agent provided by the invention has a large potential.
