The evolution of core parameters

The golden combination of torque and speed

Hard rock layer: 40kN·m torque + 20-50rpm low speed (granite penetration rate ≥4m/h)

Gravel layer: 15kN·m torque + 80-120rpm medium speed (pebble layer anti-stuck drilling efficiency increased by 60%)

The revolution of the power system

Diesel-electric hybrid: fuel consumption reduced by 30% (Caterpillar C18 + permanent magnet motor)

Highland supercharging technology: power retention rate > 90% under working conditions at an altitude of 5000m

Intelligent leap

Automatic correction system: laser gyroscope accuracy ±0.1°/10m (compared to traditional ±0.5°)

Lithology AI identification: predicting the formation through drilling pressure/speed data (accuracy 85%)

Extreme environment case

Case 1: Challenge of geothermal wells on the Qinghai-Tibet Plateau

Working conditions: altitude 4800m + Basalt (compressive strength 250MPa)

Equipment: Schramm TXD90 drilling rig (diesel-electric hybrid, maximum torque 50kN·m)

Technical solution:

Diamond impregnated drill bit (carcass hardness HRC45)

Nitrogen foam circulation system (anti-freezing and plugging)

Results: Well completion depth 1200m, water temperature 112℃, setting a plateau record

Case 2: Emergency water supply in the Sahara Desert

Requirement: 200m well completion in 72 hours (sand layer has strong fluidity)

Equipment: Bauer BG 28 (equipped with air down-the-hole hammer)

Parameter configuration:

Air compressor displacement 24m³/min (sand discharge efficiency increased by 3 times)

Casing synchronous follow-up technology (anti-collapse hole)

Results: Single well water output 80m³/day, saving 3 nomadic villages
