On February
24th, 2008,
On March 2013，China's first drilling rig with the drilling depth of 9,000 meters (ZJ90/6750) was independently developed by BOMCO.
TECHNICAL FEATURES
v Advanced AC-SCR-DC technology；
v Parallelogram substructures to be integrally raised by drawworks;
v Main brake of drawworks is hydraulic disc brake or band brake and the auxiliary brake is electro-magnetic eddy-current brake or Eaton brake;
v Rotary table is driven by compound drive or independent motor drive;
v PLC is adopted to enable logic control, monitoring and protection of the whole drilling operation, as well as data storage, printing and long-distance transmission;
v Integrated moving skid can be applied for cluster well drilling.
