Systems and Methods for Directional Pulsed-Electric Drilling

摘要: Pulsed-electric drilling systems can be augmented with a steering mechanism that shifts at least portion of bit relative to borehole centerline. Illustrative mechanisms include ball-and-socket joints(82), pivot-and-hinge joints, rotary steerable systems, and bent subs. As the (26) detaches formation material using electric pulses, detached being flushed away by flow fluid, shifting from centerline causes turn in direction bit.
