Multi-path combined high-low voltage plasma rock-breaking drill bit, drill bit apparatus and drilling method
The present disclosure provides a multi-path combined high-low voltage plasma rock-breaking drill bit, drill bit apparatus and drilling method. The multi-path combined high-low voltage plasma rock-breaking drill bit comprises: a drill bit body, insulators, plasma generators, drilling fluid outlets, plasma integrated pipelines, a drilling fluid pipe; wherein a plurality of plasma generators are distributed on the same drill bit body; the axis of the plasma generator and the axis of the drill bit body form a certain included angle; each of the plasma generators is independently connected to the ground through its respective plasma integrated pipeline and operates independently; and drilling fluid flows out of the drilling fluid outlets, takes away the heat generated by the operation of the plasma generators, thereby cooling the plasma generators.
