The invention discloses a shear-resistant bionic super-smooth surface system, a preparation method and drag reduction application thereof, and belongs to the field of underwater drag reduction. Comprising a super-smooth surface substrate, a super-oleophylic/super-oleophobic interphase surface and a lubricating oil film, the surface of the super-smooth surface substrate comprises two surface micro-structure areas with different heights, and the roughness of the surface micro-structure areas is micron-scale; the height difference ranges from 0.1 mm to 0.3 mm; the super-oleophylic/super-oleophobic interphase surface comprises a super-oleophylic surface and a super-oleophobic surface which are arranged according to a set pattern, the super-oleophylic surface is located on the upper surface of a lower surface microstructure area on the substrate, and the super-oleophobic surface is located on the upper surface of a higher surface microstructure area on the substrate; the lubricating oil is injected into the super-oleophylic surface, and after the whole super-oleophylic surface is infiltrated, a lubricating oil film with the submillimeter thickness is formed on the super-oleophylic surface. According to the super-smooth surface system, stable sealing and storage of a lubricating oil film with the submillimeter thickness are guaranteed, and the obtained bionic super-smooth surface achieves stable, efficient and anti-drag effects.
