Features of Top Head Drive Drilling System
- Being ideally suited for 2,000-4,000 meters drilling rigs
- Suitable for side-tracking, deepening old wells, directional well drilling, slim hole drilling, extended reach well drilling, and workover operations
- Being applied to well sites where electricity power is unavailable(if you can provide electricity power, we will offer the hydraulic-electricity power unit)
- To serve the well sites where the derrick structure space is limited
- Being applied to casing drilling
