LZ60 Downhole Motor is a micro downhole power drill, designed for small borehole drilling, geological exploration, coalbed methane development and other special scenarios. The following are its core technical parameters and applications
Bypass valve assembly
Motor assembly (stator and rotor)
Universal shaft assembly
Drive shaft assembly
Geological core drilling, metal mine exploration.
Coalbed methane branch well
Old well repair
Scientific drilling, polar ice or lunar simulation well (low torque demand).
1. Operation cost: about $150~300/hour (including drilling tool depreciation + mud treatment).
2. Life indicators:
Stator: 80~120 hours (soft formation) / 40~60 hours (hard formation).
Bearing: 200 hours (regular grease maintenance is required).
Notes: The actual performance is significantly affected by the well depth, well inclination, and drilling fluid performance. It is recommended to perform hydraulic parameter simulation (such as ANSYS Fluent analysis) before operation.
