Abstract

Anordning for boring, omfattende en borestreng som har et rør (10) fra en spole ragende nedover i et borehull som bores, idet røret avspoles etter hvert som boringen skjer. En nedre ende av borestrengen holder en boremotor (28) som har et hus (26) og en borkrone (32) som drives i rotasjon i forhold til huset (26). Borkronen (32) og huset (26) er skrådd i en vinkel (38). En flerplatebrems (42) som aktiveres av et stempel (44) styrer innbyrdes dreining mellom motorhuset (26) og røret (10), for å regulere boreretningen.Device for drilling, comprising a drill string having a pipe (10) from a coil projecting downward in a borehole being drilled, the pipe being reeled as the drilling takes place. A lower end of the drill string holds a drill motor (28) having a housing (26) and a drill bit (32) driven in rotation relative to the housing (26). The bit (32) and housing (26) are inclined at an angle (38). A multi-plate brake (42) actuated by a piston (44) controls the mutual rotation between the motor housing (26) and the tube (10), to control the drilling direction.
