  • Hydraulic cutting tool, system and method for controlled hydraulic cutting through a pipe wall in a well
    Patent number: 9416636
    Abstract: A hydraulic cutting tool, a system, and a method are for hydraulic cutting through a pipe wall of a pipe body. For this purpose, the cutting tool is provided with at least one cutting section comprising at least one fluid discharge body. Each such fluid discharge body comprises at least two outwardly directed discharge openings having non-parallel discharge directions directed at a common intersection point located outside the fluid discharge body. The cutting is carried out by means of an abrasive fluid being supplied, via a flow-through pipe string, to the at least one fluid discharge body from a remote location. Thereby, abrasive cutting jets will discharge at high velocity from the fluid discharge body so as to meet and disperse in the intersection point, thus weakening the further cutting ability of the cutting jets.
