Abstract
Electrocrushing drill bits comprising one or more high voltage electrodes surrounded by a ground or current return structure, which can be a ring or a comprise rod shaped (i.e. cylindrical) electrodes. Openings in the rim of the current return structure facilitate removal of drilling debris and bubbles created by the electrocrushing process out from the bottom face of the bit and up the wellbore. The high voltage electrodes can be arranged in a circle. The current return structure may partially cover the bottom face of the drill bit, thereby enclosing the high voltage electrodes in openings that may be sector shaped. Also a method and apparatus for dividing a flow of drilling fluid both to sweep drilling debris and bubbles out of the drill bit and hole and to cool high power electrical components.
