Top drive system

The top drive system provides the following technological operations:

  • rotation of the drill string while drilling, reaming borehole;
  • drill pipe threading and fastening;
  • drill pipe tripping operations;
  • casing running operations;
  • drill-string turning while drilling with downhole motors;
  • well flushing and drill-string turning;
  • well flushing during the liquidation of accidents.

The main advantage of using the top drive system is the ability to install it at any time during well drilling, practically without interrupting drilling.
