HYDRAULIC WRENCHES FOR DP AND TUBING

Basic functions and purpose of hydraulic wrenches:

  • Ensures reliable screwing and unscrewing of pipe connections.
  • Eliminates human error, reducing the risk of damage to threaded connections.
  • Increases the speed of descending and descending operations.
  • Significantly reduces drill string assembly and disassembly time.
  • Ensures safety on the rig.
  • Eliminates manual labor when handling pipe, reducing the potential for injury.
  • Controls torque when tightening joints.
  • Allows torque control to prevent pipe damage.

Where are hydraulic wrenches used?

  • On drilling rigs - when assembling and disassembling drill string.
  • When running and lifting casing - for securely connecting casing strings.
  • In field facilities - when servicing tubing.
  • In well workovers - when replacing pipe and equipment.

Types of hydraulic wrenches:

1. Top drive hydraulic wrenches (HWW)
  • Used in top drive drilling operations.
  • Allows to work with different types of pipes and provides for automatic pigging

2. Stationary Hydraulic Wrenches (SHW)
  • They are used in stationary conditions at drilling sites and repair bases.
  • They allow working with casing, drill and tubing pipes.

Advantages of using hydraulic wrenches:

  • High precision tightening of connections - minimizes the risk of depressurization.
  • Process automation - reduces dependence on human error.
  • Reduced injury hazard - eliminates the need for manual labor.
  • Versatility - can work with a variety of pipe diameters.
  • Acceleration of running and lifting operations - reduces the time required to assemble and disassemble the column.
