API Spec Hole Down Diamond Reamer 8 Inches PDC Fixed Blade Cutter Of Oil Drilling Tool 

Description :

Drilling performance is improved while borehole quality is increased when underreamed. The variety of tools available assures excellent performance in every application with operating flexibility ranging from demountable cutters to cutters that include milled teeth, tungsten carbide inserts, and polycrystalline diamond compact (PDC) cutters.

Specification

Benefits:

• Enlarges hole while drilling in single run
• Ensures smooth engagement for consistent full-gauge well bore
• Provided high stress tolerance and maximum durability
• Reduces drill string vibration
• Improves drilling efficiency , BHA stabilization
• Promotes full or low flow through BHA
• Enhance hole cleaning
• Optimizes hole opening ratios of up to 25%
• Promotes operational simplicity ,reliability
• Reduces no- productive time (NPT) and Costs  

The lower reamer provides a simple and reliable method to solve the low drilling efficiency and the

out-of-specification wellbore that may increase the expansion of the wellbore.
1) Costs are increasing exponentially.
2) Applicable to all formations and RSS
3) Simple single finite element modeling tool design
4) Special Trident PDC knife block
