Water Well Drilling Solution

Domestic and irrigation wells at Φ110–Φ250 mm, where success rate, yield and hole stability matter most.

Scope of work

Ground varies from overburden and gravel to bedrock — one well can cross several formations
Overburden collapses easily — use low pressure and slow feed with casing or mud
Casing, gravel pack and development follow — tool OD must match the casing size

Selected by hole size and duty — not the whole range

Φ185mm · hole Φ198-254 mm · 193 kg

For bedrock and deep sections: Φ185 mm body for Φ198–254 mm, high impact energy and a stable hole diameter

Φ180mm · hole Φ195-245 mm · 160.5 kg

For deep, large-diameter wells: Φ180 mm body for Φ195–245 mm, compact and quick to trip

Φ180mm · hole Φ195-254 mm · 187 kg

Where yield matters most: Φ180 mm body for Φ195–254 mm, low pressure with high air volume for strong cuttings clearance

Drop to 0.5–0.8 MPa and feed slowly in overburden, then raise to 1.0–1.7 MPa in rock

In gravel, drill with casing — casing OD 10–15 mm larger than the bit

Use a high-volume compressor on deep sections to keep return velocity ≥15 m/s
