System and method for drilling a borehole |
摘要 |
A system and method is provided for drilling a wellbore using a rotary drill bit with a bit body having a plurality of mechanical cutters to cut away formation material as the wellbore is formed and a directed energy mechanism to direct energy into the formation. The energy from the directed energy mechanism is used to enhance the cutting of the mechanical cutters by fracturing surrounding material to facilitate drilling in the direction of the directed energy. |
