A method is for isolation of a permeable zone in a subterranean well, wherein the well is provided with a pipe body. The method comprises lowering a perforation tool into the pipe body; forming holes in the pipe body along a longitudinal section; pumping a flushing fluid out through outlets in a flushing tool, into the pipe body and further out into an annulus; pumping a fluidized plugging material out through the flushing tool, into the pipe body and further out into the annulus; placing the fluidized plugging material along the longitudinal section so as to form a plug across the cross section of the well, whereby the plug fills the pipe body and the annulus; wherein at least one outlet in the flushing tool is angled non-perpendicularly relative to a longitudinal axis of the flushing tool, whereby a corresponding discharge jet also will be non-perpendicular to the longitudinal axis. |
