Abstract

Vaierlinesammenstilling (20) henges opp på en kabel (22) og senkes ned i en oljebrønn for temporær låsing til en brønnhullsaramenstilling. Låsingen fremskaffes ved kiler (48) montert i vaierlinesammenstillingen for inngrep i en komple- mentær fordypning (62) formet i bronnhullsammenstillingen og samarbeider med denne via overflaten, som er vinkelrett på den langsgående aksen til anordningen. Frigjoring oppnås ved å trekke i kabelen (22) etter at en elektrisk styrt ventil (100) har blitt aktivert. Ventilen (100) kommuniserer så med kamrene (102, 104) avgrenset av et kontrollstempel (90) på innsiden av en sylinder (86) formet i et ringformet hus (44) som holder kilene (48) . Strekket påført kabelen (42) over- føres til kontrollstemplet (90) ved en stang (42) som akti- verer en frigjoringsflens (78) som bevirker at kilene (48) trekkes tilbake.
