Zusammenfassung:	The invention discloses a reusable protective sleeve for a rubber sleeve of a compression packer and a preparation method of the protective sleeve. The protective sleeve takes a metal material as a framework and is made into an umbrella shape; the metal framework is wrapped by an oil-resistant, hydrogen sulfide-resistant and high-temperature-resistant rubber material; the rubber material comprises a fiber cloth framework material. The protective sleeve provided by the invention is kept in a contraction state in a non-bearing state, so that the protective sleeve is convenient to put down and take out; the protective sleeve can well protect the rubber sleeve, the pressure bearing capacity and the sealing effect of the rubber sleeve are greatly improved, the rubber sleeve can be continuously and repeatedly used, and the service life of the rubber sleeve is prolonged. 本发明公开了一种可重复使用的压缩式封隔器胶筒保护套及其制备方法，所述保护套以金属材料为骨架，做成伞状；所述金属骨架被耐油耐硫化氢耐高温的橡胶材料包裹；所述橡胶材料中包含纤维布骨架材料。本发明所提供的保护套在非承载状态下保持收缩状态，便于下放和取出；保护套能对胶筒进行很好的保护，大大提高胶筒的承
