ABSTRACT:
A protector for preventing tools from becoming engaged between an internally-mounted deflector guide and the inside of the body of a side-pocket mandrel. The protector includes a protrusion connected to the body adjacent to and above the deflector guide which extends into the interior of the body for blocking the space between the deflector guide and the body thereby preventing well tools from becoming stuck. The protrusion may include one or more arcuate members plug welded into the body. In addition, the protrusion may be made intergal with or connected to the upper end of the deflector guide. Preferably, at least the outer and upper edges of the protrusion are beveled outwardly towards the inside of the mandrel body for eliminating engaging shoulders. In other form, the protrusion may be formed of indentations made in the wall of the body.
