6 FAQs about [Rock drill high and low voltage conversion]

Does a high-voltage electrode drill bit affect rock dielectric breakdown?

However, its effectiveness is influenced by parameters including pulse voltage magnitude and the shape and structure of the high-voltage electrode drill bit (HVED). Currently, there is limited research on the mechanisms by which high pulse voltages (>100 kV) affect rock dielectric breakdown and the patterns of pulse voltage generation.

What is a high- and low-voltage electrode drill bit?

The high- and low-voltage electrodes of an electrode drill bit can be arranged as a coaxial cylindrical electrode structure, and a structure of multiple groups of high- and low-pressure electrodes. The electrode drill bit directly affects the energy consumed by rock breaking and the drilling efficiency.

Can high-voltage electric pulse rock-breaking technology improve drilling efficiency?

In the realm of oil extraction, high-voltage electric pulse rock-breaking technology can aid the traditional mechanical rotary drill bit in breaking rock, leading to a significant reduction in drilling costs, nearly 50%, and an enhancement in drilling efficiency (Liu et al., 2023a).

Why do high-voltage pulse drilling tools have a higher loading voltage?
