2. The basic parameters of the rig comply with the industry standard GB/T23505-2009 "Petroleum Drilling Rigs and Workover Rigs".
▋ DC electric drive rig adopts AC-SCR-DC control system and power compensation technology, enabling stepless speed regulation for drawworks, rotary table, and mud pump, thereby obtaining good drilling performance.
▋ AC variable frequency electric drive rig adopts the world's advanced VFD full digital control technology, which can adjust hoisting speed, rotary table speed, and mud pump strokes as needed to improve drilling efficiency.
▋ Adopts parallelogram integral lifting base (height 7.5m, 9m, 10.5m), enabling low-position installation of floor equipment and derrick, raised to position by drawworks or hydraulic drawworks power.
▋ Drawworks main brake adopts hydraulic disc brake with large braking torque, sensitive and reliable. Disc brake operating handle is placed in the driller's control room, greatly reducing driller's labor intensity.
▋ Rotary table adopts independent drive structure, rotary table chain box has two gears, placed below the drill floor, providing large operating space on the drill floor.
▋ Drawworks auxiliary brake can be equipped with either electromagnetic eddy current brake or Eaton brake. During tripping in, it is smooth, labor-saving, easy to control, increases reliability, and can effectively extend the service life of brake wheel (disc) and brake blocks. Drum is grooved for neat rope arrangement. Equipped with over-wind anti-collision, weight anti-collision, and digital anti-collision devices, enhancing drilling safety.
▋ Drawworks can be equipped with automatic feed drilling device.
