The Reverse Circulation Water Well Drilling Rig is a high-efficiency, large-diameter drilling machine designed for deep water well construction, large borehole projects, and complex geological formations. It is widely used in irrigation wells, pile foundation drilling, and dewatering well projects where high productivity and strong slag removal capability are required.
This Reverse Circulation Water Well Drilling Rig adopts advanced reverse circulation technology, allowing drill cuttings to be efficiently discharged through the drill pipe. This significantly improves drilling speed, enhances hole cleanliness, and ensures stable performance in demanding geological conditions.
The Reverse Circulation Water Well Drilling Rig is equipped with a powerful motor and a full hydraulic drive system, with optional electric and diesel configurations. This flexible power setup ensures strong torque output, stable operation, and adaptability to different working environments.
The Reverse Circulation Water Well Drilling Rig is suitable for soil, sand, cobble, soft rock, and loose formations. It supports a drilling diameter range of 300–1800mm and is capable of reaching a maximum depth of 300m, making it ideal for large-scale and deep drilling projects.
