DOWNHOLE TOOL WITH A DISSOLVABLE COMPONENT

摘要

A downhole tool and a method for fracturing a well, of which the method includes running downhole tool into a wellbore, the downhole tool including a ball seat including a dissolvable material and a protective layer that substantially prevents the dissolvable material from dissolving, and deploying an obstructing member into the wellbore. The obstructing member is caught by the ball seat. The method also includes performing one or more fracturing operations while the obstructing member engages the ball seat. Performing the one or more fracturing operations comprises introducing an abrading fluid to the ball seat, and the abrading fluid erodes at least a portion of the protective layer from the ball seat. The method also includes, after eroding the at least a portion of the protective layer, causing the dissolvable material of the ball seat to at least partially dissolve.
