Definitions
- Fig. 10 is a cross-sectional diagram of another embodiment of a drill string suspended in a bore hole.
- the drill bit assembly 102 may also comprise a steering motor 205 adapted to rotationally control a shaft 202 disposed within a body portion 209 of the drill bit 104 and protrudes from a working portion 210 of the drill bit 104.
- the shaft 202 may protrude from the working portion 210 6 to 20 inches.
- the shaft 202 may comprise a distal end 211 rotationally isolated from the body portion 209 and in communication with the subterranean formation 105.
- the shaft 202 and its distal end 211 may be utilized to steer the drill bit assembly 102 and drill string 100 through the formation 105.
- the second gear assembly 210 may be adapted to rotate the second rotor 307 faster than the first rotor 300.
- the impellers 304 rotate, spinning the second gear assembly 210 and the first and second rotors.
- the first and second rotors will rotate at different speeds, preferably the second rotor 307 will rotate 1.5 to 8 times faster.
- the stator vanes 305 in the turbine 201 may help increase the efficiency of the turbine 201 by redirecting the flow of the drilling fluid by preventing the fluid from flowing in a circular path down the bore 301 of the drill string 100.
