  • Patent number: 12227999
    Abstract: Disclosed are a method for manufacturing a dissolvable slip and a dissolvable slip manufactured by same. The manufacturing method sequentially comprises the following steps: (1) mixing an adhesive with solid particles and dissolvable particles; (2) coating the mixture prepared in step (1) on the surface of a slip body; and (3) curing the mixture coated in step (2). The dissolvable slip manufactured according to the manufacturing method not only has a stronger anchoring force with a wellbore inner wall, but also can adjust the dissolution rate of the slip after the completion of fracturing to enable the slip to degrade within a preset time. Further, the dissolvable slip has a better abrasion resistance, is suitable for various temperature conditions, and can still work normally in a concentrated acid or a concentrated alkali environment.
