Drilling Rigs

Covers water well and reverse circulation drilling rigs, supporting drilling depths up to 2000 meters. Reliable performance and adaptable to diverse project conditions.
Water Well Drilling Rigs

Water well drilling rigs are multifunctional hydraulic drilling units, which are widely used for drilling water wells, monitoring wells, dewatering wells, rescue wells, geothermal air-conditioning holes, as well as for coalbed methane, natural gas, petroleum extraction, and other engineering applications.

Reverse Circulation Drilling Rigs

The reverse circulation drilling rig is an efficient, environmentally friendly, and versatile rig mounted on crawler tracks. It uses advanced reverse circulation drilling technology, allowing rock dust to be effectively collected through a dust collector.

Standard water well drilling rigs provide the most suitable option. These rigs are designed for shallow formations including clay and sand, feature compact dimensions, allow flexible positioning, operate with low energy consumption, and require no complicated systems for removing drill cuttings. The water drilling rigs deliver efficient drilling for domestic shallow wells is ensured.

A reverse circulation drilling rig provides better stability in loose formations. Reverse air or water flow enables rapid cuttings discharge and maintains a stable negative pressure inside the borehole, reducing disturbance to sand or gravel strata. When combined with mud-based wall protection, collapse risks are significantly lowered, whereas standard water well rigs exhibit higher collapse probability in these conditions.

A reverse circulation drilling rig is the recommended choice. Efficient debris removal prevents cuttings buildup at deep borehole bottoms, and high-power drive systems accommodate large-diameter drilling tools. This configuration supports deep drilling more efficiently than standard water well rigs.

The water well drilling rigs, including portable and compact vehicle-mounted models, are easier to deploy. These rigs require less than 10 m² of space, do not rely on large auxiliary equipment, and can be repositioned efficiently within limited areas. Reverse circulation drilling rigs generally require more operating space due to larger machine size and associated cuttings-removal systems.

For shallow wells under 200 m, standard water well drilling rigs provide the more economical option due to lower equipment procurement or rental cost and reduced energy consumption. For deep wells over 200 m or projects involving complex formations, reverse circulation drilling rigs offer a lower long-term cost by reducing collapse risks and minimizing rework.

A reverse circulation drilling rig provides higher vertical accuracy. Hydraulic leveling systems allow continuous control of drill-rod alignment, keeping borehole deviation typically within 0.5 percent. Standard water well rigs, particularly smaller percussion types, are more susceptible to deviation caused by formation forces.

A multifunctional reverse circulation drilling rig offers greater versatility. Certain RC models support interchangeable drilling tools, including bits designed for pile construction, enabling both water well drilling and small foundation pile work. Standard water well drilling rigs are more specialized and show reduced efficiency when used for pile applications.
