Plasma deep drilling technology
Plasma deep drilling technology is one of several
High-energy plasma
High-energy plasma is a technology that targets deep drilling applications. It addresses issues related to drilling in water environments or boreholes with varying diameters.
Physical principle of electrical plasma
An electric arc is a breakdown of a gas that produces a plasma discharge, resulting from a current flowing through normally nonconductive media such as air or another gas. An arc discharge is characterized by a lower voltage than a glow discharge, and relies on thermionic emission of electrons from the electrodes supporting the arc. The electric arc is influenced by factors such as: the gas flow, inner and outer magnetic fields, and construction elements of the chamber that confines the arc. The development of plasma torches to be used as a source of the thermal plasma demands a deep understanding of the discharge chamber processes.
