Abstract

Fremgangsmåter og anordninger for å forsegle en plugg inne i produksjonsrør som pluggen er innrettet for å landes og settes i, er beskrevet. Pluggen omfatter en tetningsenhet med en tetning på pluggen som virkes på av et stempel. Brønnfluidtrykk virker på stempelet når ventilen er lukket, og beveger med det stempelet og presser tetningen til forseglende kontakt med en innvendig overflate i produksjonsrøret.
