Product Description

 

Features  :

Only four blades for the junk flowed area

Multi-optimizing force balance for cutting structure,Increasing the bit stability and cutting efficiency during drilling

Dynamic flow simulation technology is used for hydraulic design and optimizing the number and placement of nozzles to ensure optimum bottom hole flow patters and anti-balling.

Increase cuttings evacuations with available hydraulic flows .

Provide dual cutter rows without sacrificing the aggressiveness of the bit with only 4 blades,acquiring desired ROP and bit durability without bit balling
Advanced hardfacing material enhanced increased the abrasion resistant and erosion resistant.

PDC drill bit features:

1. Soft to mediun-hard formation application.

Medium parabolic crown profile and heavy cutter density provide high ROP in medium to hard formations with medium compressive strength and small abrasive layers.

1. multi-function hydraulics

The deep blade design can get high ROP in medium to hard formations and can effectively cool the bit in hrad and abrasive formations .

1. longer bit life

High intensified gage design provides for long runs on steerable system through hard and abrasive formations as teering application.
