Specification
6 straight or spiral baldes,high density cutters,deep junk slots.
Available with back row cutters to restrict cutting depth and reduce torque fluctuation and extend bit service life.
Applicable to drill in soft to medium hard formation with small abrasive layers as well as directional drilling and angle building.
Basical Specification | ||
Size | 8 1/2 inch | |
IADC code | S613 | |
Thread | 4 1/2 inch | |
Type | steel body | |
No.of Nozzles | 7 | |
Gauge Length | 2.0~2.5 | |
blade | 6 | |
Operating parameter | | |
RPM(r/m) | 60~300 | |
WOB(KN) | 20~190 | |
Flow Rate (lps) | 5~43 | |
Formation | Soft to medium hard 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.
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
