This drilling method is particularly effective for large-diameter and deep water wells, where traditional drilling machines may struggle with slow return flow or borehole instability.
The YKDRILL reverse circulation drilling rig is engineered to address these challenges by combining strong rotary performance with a high-efficiency reverse circulation system.
Compared with conventional drilling methods, the YKDRILL RC water well drilling rig significantly improves penetration efficiency while reducing the risk of hole collapse in loose formations such as sand, gravel, and clay
RC water well drilling rig offers higher penetration efficiency and better borehole quality. The direct return of cuttings through the drill pipe shortens circulation time, improves drilling speed,
With a maximum drilling depth of 200 meters and hole diameters ranging from 140 mm to 254 mm, the YKT-200 meets a wide range of groundwater drilling requirements. Its 3.6 m one-time advance length and penetration efficiency of 10–35 m/h significantly reduce drilling time and operating costs.
