Features
• Efficient drilling: The cuttings are discharged quickly, suitable for deep hole (600m level) operations, and the drilling efficiency is 30%-50% higher than that of conventional drilling rigs.
• Strong formation adaptability: High stability in complex formations such as broken zones, aquifers, and caves, and the sampling completeness rate is better than that of positive circulation.
Advantages
Reverse circulation system
Negative pressure is formed inside the drill pipe through compressed air (air lift reverse circulation) or mud pump (pump suction reverse circulation), so that the cuttings rise to the ground at high speed along the inner tube, and the outer tube transports the circulating medium (air/mud) to the bottom of the hole to cool the drill bit.
Compared with traditional positive circulation drilling rigs, the slag discharge path is more direct, avoiding repeated crushing of cuttings and reducing accidents in the hole.
