Land Drilling Rigs

SCR Drilling Rigs

Features
  • The AC-SCR-DC power transmission system is used. Through step-less speed control to drawworks, rotary table and mud pumps, users can acquire expected drilling performance;
  • The rotary table is driven independently;
  • The substructure type of sling shot allows mast and floor equipment installed at low height level then raised integrally utilizing drawworks power or individual hydraulic winches devices.

VFD Drilling Rigs

Features
  • AC-DC-AC power transmission system is used, through step-less speed control to drawworks, rotary table and mud pumps, user can acquire expected drilling performance;
  • Rotary table is driven independently with 1+1R/2+2R step-less speed;
  • Substructure type of sling shot or swing up allows mast and floor equipment installed at low height level then raised integrally utilizing drawworks power;
  • Real time communication and network is available by using PROFIBUS technology;
  • Automatic drilling is obtained by drawworks main motor or an independent motor. Intellectual position control for traveling block prevents crown block and rotary table from collision.
