Optimal design
Drill rods through the dispersion of equal strength And stress optimal design, can give full play to the Potential of drill material.
Forged connector
The connector material is forged, has an improved material density, and changes the fiber texture of the material, thereby greatly improving the general mechanical properties of the material. The end ensures that the thread is anti-corrosion, anti-sticking, and improves the fatigue resistance of the joint surface.
Application
It has applied successfully in gas exploration, drilling, geothermal well drilling and mine rescue hole and a ventilation hole construction, etc.
Applicable scope of reverse circulation drill pipe:
1 For water well drilling including complex formation, mud can be
used as flushing fluid in the easily collapsed formation to protect
the hole wall
2. It is especially suitable for drilling large diameter holes,
such as gas drainage wells, coal mine rescue wells, coalbed gas
wells and shale gas wells
3. It is not suitable for drilling in dry and leaky formations
