A drilling rig for 12,000-meter wells was successfully manufactured by CNPC's Baoji Oilfield Machinery Company Limited.

Experts from China's Ministry of Science and Technology evaluated that the drilling rig is capable of operating normally in environments ranging from equatorial regions at 55 degress to Polar areas at minus 40 degrees. The rig can automatically speedup, slowdown, brake or give an alarm according to operating conditions, dramatically enhancing the intellectualized level and safety coefficient of drilling operations.

The core parts of the rig are essentially China-made, with two invention patents being applied for and seven practical new patents being approved. Baoji Oilfield Machinery Company Limited owns the complete intellectual property rights of this 12,000-meter drilling rig.
