SYSTEM AND METHOD FOR DIRECTIONAL DRILLING UTILIZING CLUTCH ASSEMBLY

摘要

According to one embodiment of the invention, a system (100) for directional drilling within a wellbore (103) includes a drill string (101) having an upper portion (102), a lower portion (104), a bent motor (106) coupled to the lower portion (104), and a drill bit (108) coupled to bent motor (105), and a clutch assembly (200) disposed between the upper portion (102) and lower portion (104). The clutch assembly is operable to disengage the upper portion (102) and lower portion (104) of the drill string (101) and allow the upper portion (102) to rotate while the lower portion (104) does not rotate.
