Draw Works Casing Running Tool

DW Casing
Gushing Tool (DWCRT)

The DrawWorks CRT represents a unused generation of Casing Running Tools. It is a mechanically skillful tool with a modular design. TheDWCRT is organized to make up the casing, run IT in the cured, and provide rotary motion, give-and-take, and circulation at any time.  Victimization our patented compensator ignition lock mechanism (CLM), no best drive set downforce is required to determined the slips. This feature also allows theDWCRT to be set with blue torque, which provides an easy release, and the ability to attain top torque. TheDWCRT has the fewest sum up parts making it the simplest and easiest CRT on the market to hold over between jobs. One actuator head is used for sizes 4-1/2" to 20" casing reducing the number of complete tools required for your operation. Our philosophy has forever been to make our equipment so that it can be maintained on the well situation when required.

DWCRT Standard DESIGN

GRIPPING ASSEMBLIES

The ability to handle a wide tramp of mandrels (4 ½" to 26") with just one tool, has several benefits:

• A larger range of casing sizes can be accommodated
• Significant inventory and spare parts cost are reduced
• Minimal cost for additive sizes added to a fleet
• Flexibility on inventory

Mandril

• 7" Mandrel is used for all sizes from 7" to 26"
• Each sized smaller than 7" needs its own mandril of that specified sizing (4-1/2" to 6-5/8")

SLIPS

• 9-5/8" Slips are used to cover altogether sizes from 9-5/8" to 26"
• Each size smaller than 9-5/8" needs its own slips of that taxon size (4-1/2" to 8-5/8")

INSERTS

• Each size needs its own inserts of the specific size

WEAR GUARD

• 7" and little do not necessitate to wear guard as the inserts draw in privileged of the Mandrel when in the released tell
• 7-5/8" and larger sizes need its own wear guards of the specific sizing

Example: A CRT dressed for a 9-5/8" Gripping Assembly will want a 7" Mandrel + 9-5/8" BS + 9-5/8" BOI + 9-5/8" wear guard. If you need to dress the indistinguishable CRT to work with a 16" Gripping Assembly you leave use same 7" Mandrel + 9-5/8" BS and will only need to add 16" BOI + 16" wear guard.

• Wear Sentry go: Used to protect inserts during stabbing
  • 7" does non need Wear Guard arsenic the inserts retract inside of the Spindle when in released state
  • 7-5/8" – 26" each suffer their personal Wear out Guards
