An oil-soluble coated particle flow modifier, a preparation method thereof, and a use thereof in fractured-vuggy carbonate reservoirs mining. The oil-soluble coated particle flow modifier is of a core-shell structure, which has a core layer of a coated core and a shell layer of a coating agent, wherein the coated core is made of a plugging material, and the coating agent consists of petroleum resin and hollow beads. Based on the total weight of the coated particle flow modifier, the content of the petroleum resin, the hollow beads, the cotton linters, and the coated cores is 10-40 wt %, 9-40 wt %, 1-10 wt %, and 35-80 wt %, respectively. A preparation method of the coated particle flow modifier and a use of the coated particle flow modifier in fractured-vuggy carbonate reservoirs mining to improve oil recovery is also provided.
