Abstract (en)
[origin: EP2388432A2] The rig has electro-motors comprising components e.g. drill pipes drive (7), drill pipes rotation drive (8), drilling liquid processing device, pump (9) and drilling suspension mixing machine (10). A controller (1) is connected with the components of the motors via control lines (27, 28, 29, 210, 211). Work parameters for the drive and/or the rotation drive of the drill pipes are selected at a control stand (14), and the controller controls operational parameters of the components based on the work parameters. A sensor e.g. level sensor and power input sensor, is connected with the controller. An independent claim is also included for a method for distributing electric power and/or energy for operating an oil-well drilling rig.
