This is a new environmental protection drilling rig. We can directly use the existing power grid to supply power to the AC motors and then supply power to the drawworks, mud pumps and rotary table or top drive and other equipment via a gear box or chain box reducer.
The application of the industrial power grid instead of diesel oil can decrease drilling costs, reduce environmental pollution and well-site noise, improve the well-site working environment and reduce working intensity.
