Abstract
Værktøj til expandering af i hullet placerede rørformede elementer i hinanden eller i åbent hul er omtalt. En udførelsesform anvender en bevægelig konus (50), som er forspændt af tallerkenijedre til at bevæge sig i længderetningen imod en sådan for spænding og tillader spændbøsninger (40) at bevæge sig radialt ind eller ud til en forudbestemt maksimal diameter. Et frigørelsessystem tillader spændbøsnings tilbagetrækning for at undgå fasthængning ved fjernelse Ved en alternativ udførelsesform, som er mere egnet til åbenhul anvendelser, skubber gas under tryk en bevægelig konus i længderetningen i spændbøsningerne. En stationær konus er beliggende på den modsatte side af spændbøsningerne i forhold til den bevægelige konus. Spændbøsningen kører ud eller ind imellem konusserne og hæver gastrykket, når den tvinges ind. En trykaktiveret frigørelse tillader at den nedre konus forskydes nedad for at tillade spændbøsningen at trække sig tilbage for fjernelse.
Claims (10)
1, Apparatur (19,62) til ekspandering af rørformede elementer (20) omfattende: et legeme (28,64) med en længdeakse; i det mindste én spændbøsning (40,82) monteret på legemet (28) med en tykkeste del (54,85) udformet til at kontakte det rørformede element (20), hvilken tykkeste del (54,85) er udformet med en første konisk flade (52,86); en første konus (84) med en anden konisk flade (88) og forspændt i længderetningen for at bevæge den anden koniske flade (88) imod den første koniske flade (86), og en anden konus (72) monteret på legemet (28,64) modsat den tykkeste del (85) i forhold til den første konus (84) og i kontakt med den tykkeste del (85) med en konusvinkel (92) for at fremme den nævnte forspænding, som driver den tykkeste del (85) udad bort fra længdeaksen.
2, Apparatur ifølge krav 1, hvori: den anden konus (72) er udløseligt fastlåst til legemet (28,64) ved hjælp af en lås (74,76,77)..
3, Apparatur ifølge krav 2, hvori: låsen (74,76,77) frigøres hydraulisk.
4, Apparatur ifølge krav 3, hvori låsen omfatter en pal (74), som fastholdes af en bøsning (76); legemet (28,64) omfatter en indvendig passage (66) med strømningsforbindelse til bøsningen (76), for selektivt at forskyde bøsningen (76) bort fra palen (74).
5, Apparatur ifølge krav 4, hvori: passagen (66) omfatter en kontraventil (68) for at tillade trykopbygning i passagen (66) til selektivt at forskyde bøsningen (76), medens den også tillader brøndfluidtryk at komme ind i passagen (66) fortrykudligning nede i hullet.
6. Apparatur ifølge krav 2, hvori: den anden konus (72) forskydes tilstrækkeligt, når låsen (74,76,77) oplåses, således at den første konus (84) ikke er i stand til at bevæge den tykkeste del (85) af spsendbøsningen (82) udad i en retning bort fra længdeaksen
7. Apparatur ifølge krav 1, hvori: forspændingen af den første konus (84) yderligere omfatter adskillige stakkede stempler (94,96,98), som arbejder i tandem for en trykmuitiplikationsvirkning med hvert af de nævnte stempler (94,96,98) udsat på den ene side (100) for et højt tryk og på den anden side (102) foret lavere tryk.
8. Apparatur ifølge krav 7, hvori: stemplerne (94,96,98) er trykbalancerede i forhold til brøndboringens hydrostatiske tryk.
9 . Apparatur tfølge krav 6, hvori: forspændingen (84) af den første konus yderligere omfatter adskillige stakkede stempler (94,96,98), som arbejder i tandem for en trykmuitiplikationsvirkning, idet hvert af stemplerne (94,96,98) er udsat på én side (100) for et højt tryk og på den anden side (102) for et lavere tryk.
10. Apparatur ifølge krav 9, hvori: stemplerne (94,96,98) er trykbalancerede i forhold til brøndboringens hydrostatiske tryk.
