Definitions

  • the present invention Is also a method for Imaging a formation ahead of an eieetrocrushing drill bit, the method comprising providing a current pulse to a conducting loop disposed on or in an eieetrocrushing drill bit assembly, thereby generating a pulsed magnetic field which penetrates the formation ahead of the drill bit.
  • Providing the pulse preferably comprises operating ariged power circuit operating at tens of ki!ovoits and a few kiioamps and a separate pulsed power subsystem generating the current pulse.
  • the separate pulsed power subsystem preferably uses the same power source, instrumentation, charging system, and control system used during operation of the electrocrushing drill bit.
  • the communication system Is preferably located near a top of a bottom hole assembly.
  • the sensors are preferably selected from the group consisting of packaged MEMS gyroscope device, solid-state ring laser gyroscope, fiber optic gyroscope, temperature sensor, pressure sensor, B-dot probe, resistive probe, capacitive probe, probe utilizing optical effects, current transformer, E-dot probe, rotating flow meter, capacitive flow meter, inductive flow meter, venturi-type meter, and rotational pump speed sensor.

  • Fig. 81 shows nutation motion of the drill bit of Fig. 35.
  • the eiectrocrushing (EC) drilling process does not require rotation of the bit.
  • the eiectrocrushing drilling process is capable of excavating the hole out beyond the edges of the bit without the need of mechanical teeth, in addition, by arranging many electrode sets at the front of the bit and varying the pulse repetition rate or pulse energy to different electrode sets, the bit can be steered through the rock by excavating more rock from one side of the bit than another side. The bit turns toward the electrode sets that excavate more rock relative to the other electrode sets.
  • a bit with an asymmetric electrode configuration can comprise one or more electrode sets and need not comprise mechanical teeth, it should also be understood that directional drilling can be performed with one or more electrode sets.
  • the purpose of the rotating power source is primarily to provide torque to turn the teeth on the reamer and the FAST bit for drilling, it also rotates the FAST bit to provide the directional control in the cutting of a hole.
  • Another embodiment is to utilize continuous mud tubing with downhole electric power generation.
  • Embodiments of the present invention described herein may also include, but are not limited to the following elements or steps:
  • the present invention comprises a plurality of electrode sets disposed on the drill bit.

  • the used drilling fiuid and cuttings are then preferably transferred to a solids control system where the solids are removed from the drilling fluid.
  • the drilling fluid can also be transferred to a water extraction system where excess water is removed from the drilling flu id.
  • This nutation motion causes various segments of the drill bit to contact different sections of the hole rim that then cause the non-uniformities in the hole rim to be excavated by different segments of the drill bit.
  • the nutation motion preferably enables the bit to completely clear the hoie and propagate through the formation.
  • Embodiments of the present invention are directed to a drill and system for drilling that utilizes a pulsed source of electromagnetic energy downhole.

  • EM electromagnetic
  • Pulsed electric drilling technology is suited to provide such a source of electromagnetic energy because in certain systems the pulsed power system is already deployed downhoie.
  • the system enables electromagnetic evaluation of a formation downhoie, even while drilling.
  • the term loop is meant to include a circular or non-circular configuration, and a loop may be nearly closed or only partially closed.
  • a plurality of conductor loops can be oriented along the side or wall of the bottom hole assembly or near the bit or near the end of the bottom hole assembly opposite the bit so that, by changing the phasing of the current through the loops, the location of the maxima of the magnetic field can be steered through the formation.

Abstract

L'invention concerne des foreuses à broyage électrique et des méthodes d'utilisation de foreuses à broyage électrique. Les trépans de broyage électrique comprennent une ou plusieurs électrodes à haute tension entourées par une structure de mise à la terre ou de retour de courant, qui peut être un anneau ou comprendre des électrodes en forme de tiges. Des ouvertures dans le bord de la structure de retour de courant facilitent l'élimination des débris de forage et des bulles créées par le processus de broyage électrique hors de la face inférieure du trépan et leur remontée dans le puits de forage. Les électrodes à haute tension peuvent être organisées en cercle. La structure de retour de courant peut recouvrir partiellement la face inférieure du trépan, ce qui enferme les électrodes à haute tension dans des ouvertures qui peuvent être en forme de secteur. L'invention concerne aussi une méthode et un appareil d'interruption des communications entre des systèmes d'acquisition de données de fond de trou et un système de commande de surface pendant chaque impulsion de forage, ce qui réduit les parasites. Une connexion directe entre les deux systèmes permet des communications à haute vitesse, ce qui améliore la sécurité en fournissant plus en avance à l'opérateur des alertes d'un risque d'éruption de puits. L'invention concerne aussi une méthode et un appareil de division d'un flux de fluide de forage à la fois pour balayer les débris et les bulles de forage hors du trépan et du trou et pour refroidir les composants électriques de haute puissance.
