105-300mm Diameter Mobile Water Well Drilling Rigs With Flexible Mobility

Pneumatic mode specializes in hard rock and efficient rock breaking: Using medium and high wind pressure series down-the-hole impactors (working wind pressure 1.25-3.5Mpa, gas consumption 16-55m³/min), targeting hard formations such as weathered rocks and medium hardness bedrock. Through impact+rotary composite drilling, the rock breaking ability is outstanding. Compared with traditional pure mechanical drilling, the drilling efficiency of hard rock is increased by more than 50%, making it easy to conquer complex rock formations.

Mud mode ensures stable penetration of loose layers and prevents collapse: After switching to mud drilling mode, mud can be pumped into the hole through an optional mud pump to form a protective liquid film, effectively preventing collapse and burial problems in loose formations such as clay, sand layers, and silty soil. This ensures drilling verticality and well completion quality, adapting to most civilian and industrial drilling geological conditions.

One machine adapts to all geological environments: Without needing to replace core equipment, only by switching drilling modes and supporting tools, it can cover the vast majority of geological environments including loose layers, fractured layers, and bedrock. This avoids frequent equipment or process changes due to complex geological formations, reducing construction costs and schedule losses.

Outstanding drilling speed: In pneumatic mode, hard rock drilling is efficient, and in mud mode, drilling in loose layers is smooth. The overall drilling efficiency reaches 10-35m/h, with single-day completion of 30-80 meter well operations. Compared with single-mode drilling machines, operating efficiency increases by 30-40%, making it especially suitable for drilling projects with centralized water supply and tight schedules.

Auxiliary configuration improves job continuity: Equipped with a 65KW four-cylinder Xichai drilling rig engine, power output is strong and stable. Maximum turning torque of 5900N*m with switchable turning speeds of 30/120r/min, combined with 4T spindle pressure, ensures smooth drilling tool operation in both drilling modes, reducing drilling jamming and stopping probability. The 18T main lifting force with 20m/min fast lifting speed quickly completes drilling tool lifting and drill rod loading/unloading, further shortening auxiliary operation time.

Covering multiple drilling needs: Suitable for conventional requirements including industrial water supply wells, civilian living wells, and rural centralized water supply wells, as well as special scenarios such as geothermal drilling, small-scale hot spring development, and infrastructure precipitation wells. Particularly suitable for areas with complex geological conditions - including mountainous areas (hard rock formations) and plains (loose sand layers) where different drilling tasks can be completed with one equipment.

Suitable for remote and complex work environments: With ST200 four-wheel drive tire chassis design, climbing ability reaches 21 degrees. Compact external dimensions of 4.5m × 1.8m × 2.1m enable direct access to areas with inconvenient transportation such as rural areas, mountainous areas, and fields. No external power required - the 28HP truck engine ensures mobility, and the independent drilling rig power system supports field operations, allowing normal construction even in remote areas without power grid coverage.

High drilling accuracy: Dual-mode drilling relies on hydraulic control and stable power output, with minimal deviation in drilling tool operation and high drilling verticality, reducing later well pipe installation difficulty. The mud wall protection mode protects hole wall integrity, while pneumatic mode provides uniform impact, avoiding well quality problems caused by hole wall collapse or rock fragmentation. This ensures better water output and extended well service life.

Flexible configuration for different working conditions: Supports optional accessories including mud pumps, centrifugal pumps, generators, and foam pumps. For dry areas, mud pumps enhance wall protection effect; for areas without power supply, generators ensure continuous operation; for remote areas, centrifugal pumps improve water yield efficiency. These can be combined as required to meet drilling needs in different environments and reduce construction risks.
