Downhole hydraulic thread reversing system

Products Introduce

Introduction:

The downhole thread  reversing system does not rely on the workover rig's rotary table to provide torque. It is conveyed to the operation depth via the drill pipe and generates back-off torque using the energy from pumped fluids to unscrew the threads below the tool. The reverse torque produced during the tool's operation is transferred to the casing by the anchor, eliminating the need for reliance on the upper pipe string or surface equipment.

Features and Benefits:

★ Independent of surface equipment and pipe string for torque transmission

★ Extremely high back-off torque

★ Simple operation
