METHOD FOR ZONE ISOLATION IN A SUBTERRANEAN WELL

摘要

A method for zone isolation in a subterranean well (1) is described, the well (1) being provided with a pipe body (211) at least in a portion, characterized by the method including: (A) providing a plug (25) over a longitudinal section (L1) of the well (1), the plug (25) covering substantially the entire cross section (T1) of the well (1) at least in a portion of the longitudinal section (L1), so that the plug (1) fills the inside of a pipe body (211) and an annulus (5) between the outside of the pipe body (211) and a surrounding well body (7).
