105-300mm Diameter Tire Water Well Drilling Rig With Flexible Mobility

The ST200 four-wheel drive tire water well drilling rig, with its targeted design and comprehensive performance configuration, demonstrates multiple core advantages in industrial and civilian drilling, geothermal drilling and other scenarios, solving the points of traditional drilling equipment and adapting to diverse operational needs

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 16-55m ³/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 and hole protection: After switching the 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, ensuring the verticality of drilling and the quality of well completion, and adapting to the geological conditions of most civilian and industrial drilling.
One machine adapts to all geological environments: without the need to replace core equipment, only by switching drilling modes and supporting tools, it can cover the vast majority of geological environments such as loose layers, fractured layers, and bedrock, avoiding frequent replacement of equipment or processes due to complex geological formations and 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, and a single day can complete well completion operations of 30-80 meters. Compared with drilling machines with a single drilling mode, the operating efficiency is increased by 30% -40%, 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, the power output is strong and stable, the maximum turning torque is 5900N · m, the turning speed can be switched to 30/120r/min, and combined with 4T spindle pressure, it ensures smooth operation of the drilling tool in both drilling modes, reducing the probability of drilling jamming and stopping; 18T main lifting force+20m/min fast lifting speed, quickly completing drilling tool lifting and drilling rod loading and unloading, further shortening auxiliary operation time.

Covering multiple types of drilling needs: it is suitable for conventional needs such as 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. It is particularly suitable for areas with complex geological conditions - such as mountainous areas (including hard rock formations) and plains (including loose sand layers) where different types of drilling tasks can be completed with one equipment.
Suitable for remote and complex work environments: With the ST200 four-wheel drive tire chassis design, the climbing ability reaches 21 degrees, and the external dimensions are only 4.5m × 1.8m × 2.1m, which can directly reach areas with inconvenient transportation such as rural areas, mountainous areas, and fields; No external power is required, the 28HP truck engine ensures mobility, and the independent power system of the drilling rig supports field operations, allowing for 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 small deviation in drilling tool operation and high drilling verticality, reducing the difficulty of later well pipe installation; The mud wall protection mode can protect the integrity of the hole wall, and the pneumatic mode has uniform impact, avoiding well quality problems caused by hole wall collapse or rock fragmentation. The water output and service life of the well are more guaranteed.
Flexible configuration and adaptability to different working conditions: support optional mud pumps, centrifugal pumps, generators, foam pumps and other accessories; for dry areas, mud pumps can be equipped to enhance the wall protection effect; for areas without power supply, generators can be installed to ensure continuous operation; for remote areas, centrifugal pumps can be used to improve the water yield efficiency, which can be combined as required to meet the drilling needs in different environments and reduce construction risks.
