Reverse Circulation Drill Pipe Features
Efficient slag discharge: The central channel directly discharges rock debris, increasing drilling speed by more than 30%.
Strong geological adaptability: particularly suitable for drilling operations in loose and fragmented geological formations.
Good pollution control: reduce leakage of flushing solution and minimize disturbance to the pore wall.
Large caliber advantage: The supporting down the hole hammer can be used to drill holes of over 800mm.
Energy saving and consumption reduction: Compared with the same period last year, the positive circulation drilling rig saves 40% water and 25% electricity.
Advantages of Reverse Circulation Drill Pipe
01
Efficient slag discharge: Rock debris is directly discharged to the surface, increasing drilling speed by more than 40%.
02
Super adaptability: Excellent performance in complex formations such as quicksand layers/fractured zones.
03
Energy saving and environmental protection: 50% water saving compared to the same period of positive circulation, reducing mud pollution.
04
