Well packer for a pipe string and a method of leading a line past the well packer

A method of leading at least one continuous line (18) seamlessly past at least one external packer (4, 4′, 4″) along a pipe string (2) in a well (6), the at least one line (18) being led to its well position, where it has a free termination or is connected to well equipment, characterized in that the method comprises the following sequential steps:

• (a) each packer position along the pipe string (2) is connected to or constructed with an inner packer ring (8);
• (b) a number of outer packer rings (10) is arranged in logical order for subsequent sequential feeding to the pipe string (2);
• (c) the at least one line (18) is passed through all the outer packer rings (10) and further along the pipe string (2);
• (d) the at least one line (18) is connected to the inner packer ring (8) of the first, and in the operating position deepest, packer (4, 4′, 4″);
• (e) the most proximal of said outer packer rings (10) mentioned in (b) are passed along the at least one line (18) and onwards to the pipe string (2);
• (f) the outer packer ring (10) is pulled over and around the at least one line (18) and the inner packer ring (8) as a sealing sleeve, each line (18) being arranged in an axial, through-going line slot (16, 16′) between the fitting surfaces of the packer rings (8, 10);
• (g) additional piping lengths of the pipe string (2) are assembled and run into the well (6) while the at least one line (18) is fed out continuously along the pipe string (2);
• and that
• (h) steps (d)-(g) are repeated if the at least one line (18) is to be connected to several successive packers (4, 4′, 4″) along the pipe string (2).
