Product Description

The rotary table is driven by DC or AC VFD motor and the drawwoks and mud pump are driven by disel engine, which costs less than electric drive rigs and eliminates the long distance transmission and high-position rotary drive of mechanical drive rigs.

A significant difference between this type of rig and fully mechanical drive rig is that the ratary table is independently driven by electric motor, which enhances the procision of drilling operation and the quality of the well.
