  • the invention also relates to a downhole tool system comprising the wireline intervention tool string and a driving section/downhole tractor.
  • the contact between the tool string and the hard material can mean that when the machining tool comes into contact with the hard material, any vibration created between the tool string and the hard material may be amplified by the stationary hard material, as the hard material may provide a counterforce to the vibration generated in the tool string and thereby cause the vibration to be transmitted into the remaining parts of the tool string .

  • the gearing unit may provide a gearing ratio of 1 :1 to the operational tool, but may have a different gearing ratio to the vibration-generating unit, or vice versa, i.e. one of the parts may rotate at the same speed as the drive shaft. Further, the first rotational speed may be lower than the second rotational speed.
  • the wireline intervention tool string may also comprise a slip ring.
  • the anchoring section may be configured to anchor the first part to the well to prevent rotational movement of the first part.

  • the vibration-dampening unit may be arranged in a longitudinal position between the driving section and the operational tool.
