ELECTRICAL DEVICE FOR WELL STIMULATION

摘要

An electrical device for well stimulation comprising a plurality of sections configured to be assembled, end to end, to form a tool. The tool comprises first and second electrodes. The second electrode is an electrically insulated peripheral electrode of the first electrode. The first and second electrodes of the tool forming, at one of the ends of the tool, a stimulation head. Additionally, one end of a body of a first section comprises a peripheral ring that is rotatably movable and translatably immobile relative to the body of the first section. The peripheral ring comprises a thread configured to engage with a thread of the second electrode of one end of a second section.
