Abstract

A 600 kJ high-power sparker is presented. Its operating principle and structure are introduced, together with its key technology and its characteristics. The sparker is composed mainly of a high-voltage DC power supply, four banks of the energy storage capacitors, three-electrode spark gap switches, and discharging electrodes. The discharging current each group is about 100 kA at 8 kV. Also, the technical parameters are given, and its application in vertical seismic profiling (VSP) logging and cross-well seismic exploration are described briefly, the explored depths is expected to be about 4500 m
