Top Drive Drilling System (TDS)

TDS doesn’t used the drill pipe, which does not limit the length of the pipe, so it avoid to connection the drill pipe when drilling 9M.

TDS have ability to drilling 28M, the drilling tools can be smoothly raised and rotated without increasing the drilling time, especially in the directional drilling process.

TDS have the ability to drill the through the sand bridge and tight hole when no Kelly. You can connection the drilling stem in a few seconds and immediate reaming, so reduce the risk in sticking.

TDS can reduce the Qty of the connection pipe by 2/3, which can decrease the accidents.

TDS used motor to make up the connection, make-up stable. You can check the torque gauge when you operation, it can avoid mistake.

The Top Drive Drilling System is a significant development trend of modern drilling rig technology advantageous in time saving, efficiency increase of drilling rig operation, disposal of down-hole complexity and increase of mechanization and safety, which has gradually become one of the standard drilling rig configurations. It can rotate the drill pipe in the above of the Derrick directly, extend the special track down and up, than complete rotary and drilling, Circulating the drilling fluid, connection the drilling stem, make-up and break-out the pipe, back reaming etc drilling operation.

Top Drive Drilling System normally consists of body, electrical drive & control system and hydraulic drive & control system.
