Abstract
The roller drill pipe protector is designed for drill pipes which used to during drilling oil & gas wells. The mean features of this design are to first; decrease casing wear and string torque &
drag. Secondly, it helps to transfer the max. Weight on bit possible, rather than to loss it due to friction & drag in between drill string and well wall or casing. In addition.
Thirdly; it absorbs drill string shocks.

Thirdly; it absorbs drill string shocks.
Description
Specification -Invention overview:
The roller drill pipe protector design involved with decrease casing wear &
torque and drag, shocks problems affected drill string.
Disadvantages of present drill pipe protector:
-The current kinds of drill pipe protector is made from rigged rEZbber causing increasing torque and drag, also it's so easy to brake out and lost in hole which causing stuck pipe inside casing.
-It acts as a rigged component on the drill pipe, result in no shocks absorption.
Advantages of roller drill pipe t~rotector design:
-Decreasing casing wear:
It adapt drill pipe to rolling inside casing instead of friction movements while sliding or rotary mode Operations.
-Decreasing torque & drag and shocks absorption:
It Lift up the drill pipe's tool joint off casing wall and decreases the metal area contact in between drill pipe and casing, which result in drill pipe more free to rotate and transfer more weight on bit while movements down or tripping out. It decreases the cross sectional area in between drill pipe and casing or well wall, result in decreasing shocks affecting drill string while rotary mode.

Claims (5)
1-A roller drill pipe protector "figure 1 ", comprising cylindrical geometry body steel, different sizes of metal or rigged rubber balls, inside body rubber cushion, grip built in bolt screws
2-A tool as defined in claim 3 , in which the cylindrical geometry body supports the rolling balls and grapping around drill pipe body in 360 degree.
3-A tool as defined in claim 1, in which the rolling balls acts in between the roller drill pipe protector and casing wall as a rolling elements.
4-A tool as defined in claim 1, in which the rubber cushion inside the roller drill pipe protector absorbs the shocks affecting the tool while drilling operations.
5-A tool as defined in claim 1, in which the grips built in bolt screws used to tighten the roller drill pipe protector body around the drill pipe body using screw bolt. This kind of fixing method for the roller drill pipe protector is subject to change by another design or method in the future.
