Title:
METHOD FOR MANUFACTURING SOLUBLE SLIP AND SOLUBLE SLIP MANUFACTURED BY SAME
Document Type and Number:
WIPO Patent Application WO/2019/153905
Kind Code:
A1
Abstract:
Disclosed are a method for manufacturing a soluble slip and a soluble slip manufactured by same. The manufacturing method sequentially comprises the following steps: (1) mixing an adhesive with a solid particle and a soluble particle; (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 soluble 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 set time. Further, the soluble slip has a better abrasion resistance, is suitable for various temperature conditions, and can still work as normal in the environment of a concentrated acid or a concentrated alkali.
