Abstract
The present invention relates to a method and a device in wells, and preferably energy wells, for sealing thereof, said wells being of a kind comprising a well casing (1) and circulation pipes (2) extending inside said well casing, preferably for the circulation of a heat-exchange medium. According to the invention a tubular gasket (4) is fitted around the circulation pipes (2) so as to enclose the latter at least around part of their extension lengthwise and is arranged at the lower part of said well casing (1), a material (6) of a kind that expands upon its contact with a liquid, and in consequence thereof becomes sealing, being applied about the tubular gasket (4) to seal between said tubular gasket and the well casing (1).
