WR600S

💧 WR600S 600-Meter Telescopic Mast Crawler Water Well Drilling Rig

The WR600S is a crawler-mounted fully hydraulic drilling rig designed for 600-meter-class deep water wells and high-load groundwater projects. It adopts a telescopic mast structure, supports 6 m drill pipes, and is equipped with 35 T lifting force, 12000 / 6000 N·m dual-mode rotary torque, and a 132 kW Cummins engine. Compared with 500-meter-class equipment, the WR600S places greater emphasis on deep-hole drill string control, long-term continuous operation, and stability in complex formations. It is suitable for rural deep wells, agricultural irrigation, industrial water supply, mining area water supply, and general deep groundwater development.

🎯 600-Meter-Class Positioning Is Better Suited for Truly Deep Groundwater Projects

Maximum drilling depth is 600 m, with a drilling diameter of 105–400 mm. For areas where groundwater is buried deep, shallow aquifers are unstable, or greater construction margin is required, the WR600S has a wider application range than 300–500-meter-class models. The actual well depth should be determined based on local hydrogeological conditions and aquifer location. It is not recommended to treat the maximum drilling depth as a fixed target for all projects.

🪜 Telescopic Mast Balances 6-Meter Drill Pipe Efficiency and Transport Convenience

The S in the model represents the telescopic mast. During operation, 6 m drill pipes can be used directly, reducing the number of pipe connections in deep well construction; during transport, the telescopic structure can improve the overall machine profile, making loading and relocation easier. For 600-meter-class drilling, there are many pipe connections, and long drill pipes can significantly reduce auxiliary time, so the mast structure has a greater impact on overall construction efficiency.

🔩 89 / 102 mm Drill Pipes Are Suitable for Continuous Medium-Deep Hole Construction

Recommended drill pipe diameters are 89 / 102 mm, with a drill pipe length of 6 m. In 600-meter-class drilling, drill pipe weight, thread load, and hole wall friction all increase significantly. Therefore, drill pipe selection should not be based only on size, but should also consider material, connection strength, DTH hammer specifications, and the main hole diameter. During construction, thread wear and drill pipe bending should be checked regularly.

💪 35 T Lifting Force Provides Greater Margin for Deep-Hole Drill Strings and Casing Handling

The WR600S has a lifting force of 35 T and an axial pressure of 6 T. In deep-hole construction, drill pipe self-weight, hole wall friction, casing weight, and local diameter reduction all increase pull-out loads. Greater lifting capacity facilitates normal tripping, DTH hammer recovery, and some casing operations. If pull-out resistance suddenly becomes abnormal, the hole should first be cleaned and the hole wall condition assessed, rather than directly relying on maximum lifting force to force handling.

🔄 12000 / 6000 N·m Dual-Mode Torque Adapts to Different Loads

The rotary system has a maximum torque of 12000 / 6000 N·m, corresponding to maximum speeds of 90 / 180 r/min. Larger hole diameters, hard rock, and high-friction hole sections are better suited to low-speed high-torque conditions; when resistance is lower or the drilling tool load is lighter, a higher speed can be selected. Actual construction should be dynamically adjusted according to the drill bit, DTH hammer, cuttings return, and rotary load.

🚀 33 m/min Fast Lifting and 55 m/min Fast Feed

Fast lifting and feed are mainly used for power head return, drill pipe connection, and other non-drilling actions, which can reduce auxiliary time. The reference drilling efficiency in the data is 10–35 m/h. The actual penetration rate in rock formations still depends on formation hardness, hole diameter, DTH hammer, air compressor displacement, and operating method.

🌾 Deep Farmland Irrigation Wells and Large-Scale Agricultural Projects

For farmland, orchards, and large-scale planting areas with deep groundwater levels, 600-meter-class equipment can provide greater depth margin for water exploration. The 6 m drill pipe is suitable for continuous construction of multiple medium-deep wells, reducing pipe connection frequency. When completing the well, the hole diameter and well structure should be determined based on irrigation area, planned water output, well casing size, and pump type.

🏠 Rural Deep Water Wells and Remote Community Water Supply

In villages and remote areas where centralized water supply coverage is insufficient or groundwater is buried deep, the WR600S can be used for village-level water supply wells, schools, clinics, and small community groundwater development. The 600-meter-class drilling depth provides greater formation coverage, but the final construction depth should still be determined by hydrogeological data and the actual water-producing layer.

🏭 Industrial Park and Large Project Water Supply

Factories, industrial parks, construction camps, and infrastructure projects may require long-term stable groundwater sources. The WR600S can be used for production auxiliary water, equipment cleaning, construction water, and general industrial water supply wells. For long-term pumping projects, well casing, screen pipes, and pump type should be reasonably designed after drilling is completed based on the aquifer and water output.

⛏️ Mining Area Domestic Water Supply, Dust Suppression, and Auxiliary Production Water

Mining areas often have characteristics such as a high proportion of hard rock, complex road conditions, and scattered hole positions. The WR600S crawler chassis, 132 kW power, and 35 T lifting force are more suitable for deep well construction in mining areas. It can be used for mine camp water supply, dust suppression, equipment cleaning, and auxiliary production water. For mine dewatering projects, separate hydrological design should be carried out.

💨 1.2–3.5 MPa Working Air Pressure Is Suitable for Medium and High Air Pressure DTH Hammers

Recommended working air pressure for DTH drilling is 1.2–3.5 MPa, with air consumption of 16–55 m³/min. In 600-meter-class deep holes, compressed air is responsible not only for impact but also for ensuring bottom-hole cuttings removal. When hole depth increases, hole diameter becomes larger, rock formation becomes harder, or altitude rises, the actual required displacement may increase. Therefore, the air compressor must be matched separately according to the project.

💎 Hard Rock Construction Such as Granite, Limestone, and Sandstone

After entering relatively intact hard rock, medium and high air pressure DTH hammers can be used for drilling. In hard rock conditions, DTH hammer lubrication, stable air volume, and timely cuttings removal should be ensured. If cuttings return decreases significantly, torque increases, or air pressure fluctuates, the hole should be cleaned in time and the drill bit and DTH hammer condition checked.

🌦️ Weathered Rock and Alternating Soft-Hard Formations

Weathered rock often has a faster penetration rate, but the hole wall is prone to caving and diameter reduction. Alternating soft-hard formations cause frequent changes in rotary torque and feed resistance, so rotation, feed, and hole cleaning frequency should be adjusted in time. If the upper weathered layer is thick, casing can be used to stabilize the upper hole section and reduce hole wall problems in the later stages of deep drilling.

🌧️ Soil, Clay, Sand, and Gravel Overburden

The WR600S supports mud rotary drilling. In upper soil, clay, sand, and gravel layers, priority should be given to hole stabilization, cuttings carrying, and hole wall protection. Mud, casing, or other wall protection methods can be used. Switching to DTH drilling after entering relatively stable rock formations is more conducive to ensuring the quality of deep well completion.

🧱 Fractures, Broken Zones, and Air-Loss Formations

Broken zones are prone to caving, diameter reduction, air loss, and sticking. During construction, excessively fast feed should be avoided, continuous hole cleaning should be maintained, and foam or casing should be used according to site conditions. If air loss is severe, the fracture and cavity conditions should be assessed rather than simply increasing air compressor pressure.

💧 Aquifers and Strong Water Inflow Hole Sections

After entering the main aquifer, groundwater will change the DTH hammer cuttings removal and downhole pressure conditions. The depth of the main water-producing layer should be recorded, and air supply, hole cleaning, and casing methods should be adjusted according to water inflow. During well completion, screen pipes and sealing sections should be reasonably arranged based on the aquifer location.

🚜 3 km/h Crawler Travel Is Suitable for Mining Areas and Field Relocation

The equipment travel speed is about 3 km/h, with a maximum climbing angle of 21° for reference. The crawler chassis is suitable for gravel ground, mining area roads, and generally uneven sites. Since the overall machine weight reaches 12.5 T, ground bearing capacity, slope, and wet slippery conditions should be confirmed before relocation. Direct high-load travel on soft ground should be avoided.

🦵 1.6-Meter Hydraulic Outriggers Improve Deep-Hole Operation Stability

The hydraulic outrigger stroke is 1.6 m, which can be used for equipment leveling and stable support. 600-meter-class drilling takes longer, and overall machine stability directly affects mast stress and hole deviation control. On soft ground, pads should be used to ensure even outrigger force and avoid settlement after long-term operation.

⚡ 132 kW Cummins Engine Provides Power for Heavy-Load Continuous Operation

The WR600S uses a 132 kW Cummins engine to provide power for rotation, feed, crawler travel, and auxiliary hydraulic systems. Deep-hole, hard-rock, and large-diameter construction lasts for a long time, so engine cooling, air filtration, and fuel system maintenance should be strengthened. For projects with heavy dust, the cleaning frequency of the radiator and filter elements should also be increased.

🧵 2.5 T Auxiliary Winch Is Suitable for Heavier Drilling Tools and Accessories

The auxiliary winch has a lifting force of 2.5 T and can be used for handling DTH hammers, drill pipes, casing tools, and other on-site accessories. 600-meter-class projects have heavier supporting drilling tools. Using the winch can reduce manual labor intensity, but the rated load must be controlled during lifting, and personnel must stay away from suspended objects and the direction of wire rope force.

📦 12.5 T Overall Machine Transport Requires Advance Planning

The overall machine weight is about 12.5 T, and the overall dimensions are about 6.73 × 2.1 × 2.63 m. During transport, a suitable flatbed truck should be arranged according to vehicle load, road width limits, and height limits, and the telescopic mast locking, equipment fixing points, and drill pipe bundling status should be checked. After arriving at the site, sufficient space for mast extension should also be reserved.

🧰 Mud Pump, Centrifugal Pump, Generator, and Foam Pump Are Optional

Mud pumps, centrifugal pumps, generators, and foam pumps can be optionally configured according to project formations. Projects with more loose layers place greater emphasis on the mud system, hard rock projects mainly match air compressors and DTH hammers, and foam can be used as an auxiliary in formations with severe air loss. Configuring according to actual working conditions can reduce unnecessary equipment investment.

⚠️ Precautions for 600-Meter Deep-Hole Construction and Maintenance

Before starting work each day, check the engine, hydraulic system, telescopic mast, crawler, outriggers, auxiliary winch, and high-pressure air pipes; during deep-hole construction, continuously record changes in air pressure, torque, cuttings return, water return, and pull-out resistance; when using 6 m drill pipes, ensure the mast is fully extended and reliably locked, and stop the machine for inspection in case of abnormalities.

Due to differences in actual geological conditions, downhole tools, drilling angle, and operating methods, the final drilling efficiency, drilling depth, and well completion results should be based on on-site working conditions.
