Abstract
Anordning for dannelse av en dyp boring ved en dreie- spyleprosess, ved hjelp av en borestreng (1) med et dreieboreverktøy (2) på den nedre enden av borestrengen (1) og med en drivanordning (3) for boringen, med i det minste et vektelement (4) i den nedre del av borestrengen (1) og med i det minste en borestang (5) og i det minste et hydrostatisk frakoblingselement (6) i borestrengen (1). Et boretårn (7) er utstyrt med kroker (8), heiseverk (9), borestang- manipuleringsinnretning og et spyleanlegg med spylepumpe (10). Det hydrostatiske frakoblingselementet (6) er montert i borestrengen (1) ved den øvre enden av vektelementet (4). Det hydrostatiske frakoblingselementet (6) oppviser en tetningsanordning (11), som hovedsakelig bare er tilpasset arbeidstrykket til spylepumpen (10).
