METHOD FOR DOWNHOLE CUTTING OF AT LEAST ONE LINE DISPOSED OUTSIDE AND ALONG A PIPE STRING IN A WELL, AND WITHOUT SIMULTANEOUSLY SEVERING THE PIPE STRING

摘要

A method is for cutting of at least one line disposed along a pipe string in a well. The method includes (A), using a cutting tool for selective cutting activation and provided with at least one cut-forming means for cutting in a radial direction outward from the cutting tool; and (B) lowering the cutting tool to a longitudinal section where the cutting is to be carried out. In (A), a cutting tool is used for controlled cutting in a peripheral direction and distributed in an axial direction relative to the cutting tool. The method further includes (C), activating the cutting tool and cutting, in the radial direction through and past the wall of the pipe string, at least one peripherally extending hole collectively covering the entire circumference of the pipe string, and also distributing the hole in the axial direction.
