Formation | Soft and medium soft layer,high abrasive formation |
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.
2. 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 .
3. longer bit life
High intensified gage design provides for long runs on steerable system through hard and abrasive formations as teering application.
PDC ROCK BIT Option Features:
PDC Cutters
Different features of PDC cutters can be chosen in different wells or formations for maximizing both drill efficiency and economic
Gauge length
Short:Improved bit steerability and tool face control for directional or horizontal drilling, reduce slide section by achieve builds more quickly.
Extend:Enhances bit stability and allows more area for gauge protection components, improves bole hole quality.
Active gauge
Protect the gauge and improved hole quality
