Abstract
A combined drill bit based on the electro-pulse-drilling technology includes a PDC bit, a ground electrode, a high-voltage electrode, a high-voltage electrode spring, an electrode drill bit spring, electrode screws, an insulating rod, an insulating spline sleeve, a high-voltage cable connector, an insulating limit cover, a lower bearing, an upper bearing, an end cover, and a conical connecting component. The combined drill bit combines the PDC bit and the electro-pulse-drilling technology, can not only overcome shortcomings of poor wall quality and difficulty in controlling borehole trajectory in process of electro-pulse drilling, but also improve the efficiency of deep-well drilling.
