PDC Hole Reamer of 8-1/2inch 6 Blades of API Connection BOX and Pin

Description :

Underreaming enhances drilling performance and improves borehole quality. There is a wide range of tools available that guarantee exceptional performance in various applications. These tools offer operational flexibility, including demountable cutters, cutters with milled teeth, tungsten carbide inserts, and polycrystalline diamond compact (PDC) cutters.

By incorporating underreaming techniques and utilizing these advanced tools, the drilling process becomes more efficient, resulting in enhanced performance. The use of demountable cutters allows for easy replacement and maintenance, ensuring uninterrupted drilling operations. Cutters with milled teeth offer excellent cutting capabilities, enabling efficient penetration through different formations. Tungsten carbide inserts provide enhanced durability and wear resistance, prolonging the lifespan of the tools and maintaining consistent performance.

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

Whether it is expanding an existing well bore or reaming while drilling. Regardless of whether it is

formed or operated, the reamer can provide the greatest durability parameters.This universal tool

includes a single body modeled by finite element engineering design analysis (FEA) to ensure

a robust low-quality design.This concentric symmetrical mass balance design provides the best
opening ratio, up to 25%, and increases the flow around the tool,To enhance hole cleaning and reduce

downhole vibration.The design has excellent mechanical advantages. The reamer is a spherical

drop or pass that is opened and closed by one of two hydraulic activation methods.Through the pre-set nozzle,

in the nozzle, the fully controlled pressure drop activates the tool. Either way, the reamer can be completely,

Open consistently, providing simple, reliable and cost-effective hole enlargement at one time.

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.
