Soil investigation drilling rig

wellwater wellportable

Overview
Getting the right drilling machine saves both time and labor. A standard portable well drilling rig drills to depths of 150 meters with hole diameters from 75 mm to 300 mm. Available configurations include wheel, crawler, electric, or tractor-mounted units to match terrain, power availability and budget.

Key capabilities & notes
Standard capability: 150 meters max drilling depth (upgradable). Typical hole diameters: 75–300 mm (commonly up to 254 mm). Typical drilling advance rate around 10 meters per hour under normal conditions. Units may include electric start and built-in mud pump as standard options.

Applications

• Farm irrigation and agriculture: drill water wells up to 150 m to secure water for crops and orchards.
• Residential water wells: compact wheeled or crawler units fit into backyards with minimal disruption.
• Small construction work: dewatering, soil sampling, and small foundation holes.
• Off-grid remote sites: tractor-mounted units can be fitted with a 30 kW generator for self-contained power.

Power & configuration options

• Wheel and crawler diesel units: example baseline uses a Changchai 22 HP engine with hydraulic legs; standard drilling depth 150 m. Depth can be increased to ~200 m by upgrading to 28 HP, 30 HP or 35 HP engines.
• Electric well drilling rigs: suitable where grid power exists. Typical setups: 220 V/3.5 kW for ~100 m; 380 V versions available at 4 kW, scalable to 5.5 kW or 7.5 kW for deeper work.
• Tractor-driven units: can drill larger diameters (up to ~400 mm) and reach depths around 130–150 m; use φ76 mm drill rods and fit within standard 20GP container dimensions for shipping.

What to check before ordering
Ensure required items are included: electric start, built-in mud pump, appropriate rod and bit types for ground conditions, and verify shipping weight/packing size for logistics.

Field example
Example: small crawler diesel rig with hydraulic legs and a 22 HP engine used to drill a 120 m water well on a hillside orchard. The rig navigated tight access paths, advanced at ~10 m/h and reached fresh water within 2 days in that case.

Buyer FAQ (selected)

• Q: Can this portable drilling rig cut through hard rock?
  A: Yes. The unit can be fitted with rock bits or tricone bits for hard layers. This model does not support DTH hammer bits.
• Q: Is on-site assembly required? Is field installation included?
  A: The unit is assembled prior to shipping. On arrival, connect drill rods and bit and the rig is ready. Remote technical support is commonly provided for setup guidance.
