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).Device for forming a deep bore in a rotary flushing process, by means of a drill string (1) with a rotary drilling tool (2) at the lower end of the drill string (1) and with a drilling device (3) for the drilling, with at least one a weight element (4) in the lower part of the drill string (1) and with at least one drill rod (5) and at least one hydrostatic disconnect element (6) in the drill string (1). A drill tower (7) is equipped with hooks (8), hoists (9), drill bar manipulator and a flushing system with flush pump (10). The hydrostatic disconnecting element (6) is mounted in the drill string (1) at the upper end of the weight element (4). The hydrostatic disconnecting element (6) has a sealing device (11), which is adapted mainly to the working pressure of the flushing pump (10).
