Drilling Equipment For Water Well Using Air Compressor For Rural Irrigation

Overview of ST-350 Pneumatic Drilling Rig

ST-350 Pneumatic Drilling Rig Parameter:

I. Core Configuration: Power and Structural Design Adapted for Medium-Deep Hole Drilling

• 1.Power System: Equipped with a 50-120kW diesel engine or electric motor, combined with a high-pressure hydraulic pump, it can output a torque of 1500-3000N·m and an impact force of 20-50kN. It can not only drive drilling tools to rotate and cut through thick sand layers and gravel layers but also break moderately weathered rock (e.g., limestone, sandstone) within a depth of 300 meters through the combined action of "hydraulic impact + rotation", avoiding the problem of "inability to drill in deep holes".
• 2.Drilling Tools and Hoisting System: Equipped with high-strength geological drill pipes (single length 3-6 meters) with a diameter of Φ89-127mm, which can withstand the axial pressure and torque during deep hole drilling. The hydraulic winch with a lifting capacity of 8-15 tons can quickly lower and lift drill pipes, reducing the auxiliary time for deep hole operations — it only takes 1-2 hours to lift the drill string from a 350-meter depth.
• 3.Body Structure: Adopts a foldable or split-type frame. After unfolding, the whole machine has strong stability (equipped with 4-6 hydraulic outriggers for leveling, with a horizontal error ≤0.5%), avoiding hole deviation caused by the machine shaking during deep hole drilling. Some models can be equipped with a crawler chassis, adapting to muddy and gentle slope terrain in the field, and have better flexibility in entering the construction site than large deep well drilling rigs.

II. Core Advantages: Accurate Adaptability to Medium-Deep Water Well Scenarios

• 1.Drilling Efficiency: For 100-200-meter sand layers, the average daily drilling depth can reach 30-50 meters, and a well can be completed in 3-5 days; for 200-350-meter formations containing moderately weathered rock, with a hydraulic impactor equipped, the average daily drilling depth is 15-25 meters, and drilling can be completed in 10-15 days — which is 40%-60% more efficient than small-sized rigs at the same depth.
• 2.Depth Compatibility: The drilling depth can be flexibly adjusted. It can be used as a shallow-to-medium well within 200 meters (e.g., centralized water supply wells in rural areas) and can also drill to a full load depth of 350 meters (e.g., production water wells in small industrial parks). It can cover multi-depth needs without replacing equipment, reducing equipment investment costs.
