Downhole seismic energy source, the high voltage electrode UNIT AND UNIT LOW Electrode

摘要

The utility model relates to a means for generating seismic energy, in particular to electro-discharger. The apparatus comprises a housing 1, a high-voltage electrode node 2, node 3, low voltage electrode, in which an opening 4 for feeding a wire 5 interelectrode space. The housing 1 comprises a main body 6, edge portion 7 and connecting said bridge portion 8. These portions 6, 7 and 8 of the body 1 are integrally formed. Node high voltage electrode 2 is located in the main part 6 of the housing 1. The low-voltage electrode assembly 3 located in the end portion 7 of the housing 1. In the housing wall 1 a through hole 9 extending through the main portion 6, plug 7, and the end portion 8. The opening 9 is intended for placing wiring. 2 the high voltage electrode assembly downhole seismic energy source electrode 10 comprises two disks 11 and 12 of dielectric material, a sleeve 13, the conical sleeve 15. Node 3, low voltage electrode downhole seismic source energy comprises a contact element, a sleeve with a projection and the conical portion and the guide tube. Technical result: increased rigidity and electrical safety.
