摘要: A method for plugging a subterranean well (6), comprising the steps: running perforating tool (1) into and positioning 5 in section (L) to be plugged; operating create plurality of holes (10) part (5) casing (4) located section; surge (2) well; lower pressure inside flowing fluid from an annulus (11) between 0 formation (7) through (10); pumping fluidized material via tubing string (9). There is also provided use well, having chamber (20) flow barrier element (23), where (23) valve or breakable restriction, being configured upon opening (23).
