Variable Frequency Electric Driven Drilling Rig

The variable frequency electric driven drilling rig is also called digital control VF rig.

Main Features
1. The meticulous design of our variable frequency electric driven drilling rig combines electromechanical and digital concepts. Advanced technologies have been poured into design of every single structure of this drilling machine. Customers benefit from reliable performance, exceptional transport efficiency, cost effectiveness and HSE compliance.

2. This drilling equipment is compatible with slingshot and telescoping substructure. The slingshot type allows for lower-placed installation of drilling platform equipment and driller control room, etc. As for telescoping type, drilling platform can reach as high as 10.5m, which is more applicable for exploration and development of high pressure gas well.

3. Driller control room is isolated with drilling platform, and utilizes independent hydraulic lifting device, thus preventing controlling components and instrument from being impacted by platform vibration.

4. Our variable frequency electric driven drilling rig allows for collection, display, store, print, remote monitoring and management of control and drilling parameters. Operatives are able to control top drive system via touch screen located at driller’s seat. Efficient yet simplified control system is the perfect alternative to traditional operation method.

5. Taking advantage of variable frequency technology, our drawworks delivers maximal torque output when rotation speed is at zero. As a result, the lifting system on this drilling machinery offers enhanced holding and lifting functions, whereby more flexible and accurate control can be implemented to drilling pressure, bit speed, pump pressure and displacement.
