Advantages Of Rotary Drilling Rig
Increased Flexibility
The lightweight modular design makes the drilling rigs easy to install and relocate, in turn, allowing greater operational flexibility for adaptation to different job sites.
Higher Automation
Rotary drilling rigs are fully self-propelled hydraulic drilling rigs; some are equipped with computer operating systems. They have many advanced automatic features that allow a high level of flexibility on operations and increased productivity.
Faster Drilling
Rotary drilling rigs can be configured with different drill bits according to strata. The long drilling tube is suitable for working in clay soil to speed up drilling. The short drilling tube is suitable in strata containing sand and cobble for better control of drilling speed.
High Operational Efficiency
Rotary drilling rigs use drilling muds to lubricate, cool and clean the drilling bit, control down hole pressures, stabilize the hole wall and remove drill cuttings, thus allowing better penetration rates and higher operational efficiency.
More Eco-Friendly
Rotary drilling rigs keep the job site clean with low environmental pollution. They generate smaller vibrations and operate with less noise.
