Abrasive slurry delivery apparatus and methods of using same

A method of inhibiting slurry erosion of an abrasive slurry delivery apparatus having an outer wall with outlet ports extending there through the method comprising the steps of:

• providing replaceable inserts of abrasive resistant material having a peripheral edge portion;
• removably mounting the inserts in the outlet ports of the outer wall of the abrasive slurry delivery apparatus in a manner such that the peripheral edge portions of the inserts protects the outlet ports from erosion due to slurry material being forced outwardly there through;
• positioning the abrasive slurry delivery apparatus in a subterranean well and flowing abrasive slurry material through the outlet ports;
• thereafter removing the delivery apparatus from the well;
• and
• removing and replacing the inserts in the outer wall of the delivery apparatus.

A method of inhibiting slurry erosion of the peripheral edge in a subterranean tool, the tool having a tubular structure with a side wall section, at least one outlet opening defined by a peripheral edge in the side wall section, the method comprising the steps of:

• providing at least one replaceable insert of abrasive resistant material for protecting the peripheral edges;
• removably mounting the insert in the side wall of the tubular structure such that the at least one insert protects the at least one peripheral edge from abrasive slurry material being forced outwardly therethrough;
• positioning the tubular structure in a subterranean well;
• flowing abrasive slurry material through an internal passage of the tubular structure and through the at least one outlet opening;
• thereafter removing the tubular structure from the well;
• and
• removing and replacing the inserts in the side wall of the tubular structure.
