Abstract
An example laser tool that operates within a wellbore is configured to combine a purging medium and a laser beam. The laser tool includes an integrator configured to receive the laser beam from a laser head and to combine the laser beam and the purging medium. A conduit is configured to generate a laminar flow from the purging medium and to produce an output that includes the laminar flow and the laser beam. The output is directed by the conduit towards a target within the wellbore. At least part of the laser tool is configured for rotation to cause the output to rotate during application of the output to the target.
Claims21
A laser tool configured to operate within a wellbore, the laser tool comprising:
- an integrator configured to receive a laser beam from a laser head and to combine the laser beam and a purging medium;
- and
- a conduit to generate a laminar flow from the purging medium and to produce an output comprised of the laminar flow and the laser beam, the output being directed towards a target within the wellbore;
- where at least part of the laser tool is configured for rotation to cause the output to rotate during application to the target.
A method of operating a laser tool, comprising:
- combining a laser beam and a purging medium in a turbulent flow;
- generating a laminar flow from the turbulent flow, the laser beam being contained within the laminar flow;
- and
- rotating the laser tool while outputting the laser beam and the laminar flow from the laser tool towards a target within a wellbore.
