Abstract

Pressurised well liner consists of a closed tube perforated over the length required to match the pressure zone in a well, the perforations being closed by hollow plugs having external flanges and projecting into the tube from outside. The liner is run into the well through a pressure sealing device at the wellhead, such as a stripper rubber or rotating head. When the liner has been properly positioned in the well, a cutting or scraping tool is run down the inside of the liner to remove the closed end of each plug projecting into the liner.
