Abstract

The purpose of this Device or Tool is to protect operational conduit/control line running along downhole tools. The features of this is it does not go completely around the tubing, it does not thread onto the tubing, it allows 360 degree rotation without set screws, and the nuts that attach the lug to the device or tool will lock the lug in place and prevent rotation by means of friction or feature intended to prevent rotation. Also, this design reduces the amount of area blocking fluid flow and therefore optimizes the fluid bypass. The old method of attaching these protectors is to thread an eccentric piece onto the end of a downhole assembly. The benefit of the old design is its strength. One shortcoming of the old design is that it needed a spotface for the set screws to sit in to prevent rotation. The spotface is added in the shop, but there are times that the lugs have to be rotated in the field to line up with the rigid conduit. This design maintains the strength of the thread design by nesting it in a recess on the OD of the device or tool. The major benefit of this design is that it can be rotated and it locks itself into place at any angle without the need for spotfaces.
