Definitions

  • Recirculation equipment 18 pumps drilling fluid from a retention pit 20 through a feed pipe 22 to kelly 10, downhole through the interior of drill string 8, through orifices in drill bit 26, back to the surface via the annulus around drill string 8, through a blowout preventer and along a return pipe 23 into the pit 20.
  • the drilling fluid transports cuttings from the borehole into the pit 20, cools the bit, and aids in maintaining the borehole integrity.
  • a telemetry interface 36 provides communication between a surface control and monitoring system 50 and the electronics for driving bit 26.
  • a user can interact with the control and monitoring system via a user interface having an input device 54 and an output device 56.
  • Software on computer readable storage media 52 configures the operation of the control and monitoring system.
  • Fig. 2 shows a close-up view of an illustrative formation 60 being penetrated by drill bit 26. Electrodes 62 on the face of the bit provide electric discharges ("sparks", or “arcs") to extend the borehole 16.
  • sparks or "arcs"
  • a high-permittivity fluid drilling fluid flows from the bore of the drill string through one or more ports in the bit to pass around the electrodes and return along the annular space around the drill string.
  • Reverse circulation embodiments reverse the fluid flow direction.
  • the fluid serves to communicate the discharges to the formation and to cool the bit and clear away the debris.
  • a rotary-steerable system may be adapted for use in a pulsed-electric drilling system to keep the bit pointed at a desired orientation as the bit rotates.
  • a bent-sub can be used to position the bit at a fixed deviation from the borehole centerline, with steering accomplished by rotating the bit so that on average the deviation is zero when straight-ahead drilling is desired, and halting rotation when it is desired to drill a curve.
