APPLICATION / CONSTRUCTION DRILLING
Construction Drilling
APPLICATION OVERVIEW
Hold the planned path from main bore to branch hole.
Directional gas-drainage branch holes place a different demand on the bit: the cutting structure must respond when deviation begins, remain stable as the path develops, and keep the bore open for the drilling assembly.
01
Initiate direction
A responsive cutting face helps the drilling assembly begin the planned deviation without introducing an abrupt change in cutting behavior.
02
Maintain stability
Balanced engagement supports a steady response while the branch-hole path is built and held through the target interval.
03
Keep the bore clean
Open waterways and continuous flushing help move cuttings away from the face and preserve an unobstructed drilling path.
BRANCH-HOLE PATH
Build direction progressively—then hold the branch.
The bit works as part of the drilling assembly. Its role is to deliver a consistent cutting response while the system initiates deviation, develops the branch trajectory, and continues along the planned drainage interval.
01 / MAIN BORE
Establish stable face
02 / INITIATE DEVIATION
Begin the planned deviation
03 / BUILD & HOLD
Develop and maintain the branch
04 / DRAINAGE BRANCH
Continue with reliable bore cleaning
RECOMMENDED BIT CONFIGURATIONS
Two flat-top configurations for directional branch-hole drilling.
Choose the cutting face according to how the drilling assembly must initiate direction, distribute cutter engagement, and move cuttings through the planned gas-drainage branch.
Multi-Wing Flat-Top PDC Bit
Engineering Advantages
- STABLE MULTI-WING ENGAGEMENT
- CONTROLLED TORQUE RESPONSE
- RELIABLE BORE CLEANING
At a glance
- Formation / Operating Conditions
- Soft to medium-hard formations
- Size Range
- Project-specific configuration
Product Details
For directional drilling and gas-drainage branch-hole programs, the multi-wing flat-top configuration distributes cutting engagement across the face to support a stable response as the assembly builds and holds the planned path. Cutter arrangement, connection, and waterways remain project-specific.
Flat-Top PDC Bit
Engineering Advantages
- COMPACT FLAT-TOP CROWN
- CONTROLLED STEERING RESPONSE
- CONTINUOUS BORE CLEANING
At a glance
- Formation / Operating Conditions
- f ≤ 10
- Size Range
- Φ56–Φ120 mm
Product Details
For directional drilling and gas-drainage branch holes, the flat-top crown supports a controlled steering response when the assembly must initiate deviation and follow a planned path. Connection, cutter arrangement, and hydraulic details are matched to the drilling assembly and formation.
SELECTION GUIDE
Choose by the directional objective, not diameter alone.
Both configurations support directional drilling. The better fit depends on how the assembly must initiate deviation, distribute cutting engagement, respond to torque, and clean the branch hole.
Configuration 01
Multi-Wing Flat-Top
For branch-hole programs where distributed cutting engagement and a stable face response are the primary design objectives.
- Stable multi-wing engagement
- Controlled torque response
- Reliable bore cleaning
Configuration 02
Flat-Top
For branch-hole programs where a compact crown and controlled steering response are the primary design objectives.
- Compact flat-top crown
- Controlled steering response
- Continuous bore cleaning
