Abstract

Oppfinnelsen angår en sikkerhetspakning for brønner. Ifølge oppfinnelsen omfatter sikkerhetspakningen, i kombinasjon, et lokk (7) som har en overflate vendt mot brønnhullets vegg, og en streng (20) av et materi- ale som svulmer opp etter kontakt med en væske, hvilken streng er satt inn i mellomrommet mellom veggen og den nevnte lokkoverflate.The invention relates to a safety gasket for wells. According to the invention, the security gasket comprises, in combination, a cover (7) having a surface facing the wall of the wellbore, and a strand (20) of a material which swells upon contact with a liquid, which string is inserted into the space between the wall and said lid surface.
