| 摘要 |
<p>The present invention relates to an electrical device (10) for well stimulation, said device comprising a plurality of sections (11), said sections being suitable for being assembled, end to end, such as to form a tool (10a) comprising a first and second electrode, said second electrode being an electrically insulated peripheral electrode of said first electrode, said first and second electrodes of the tool forming, at one of the ends of the tool, a stimulation head (15). Additionally, one end of a body of a first section (11a) comprises a peripheral ring (16) that is rotatably movable and translatably immobile relative to said body of said first section, said peripheral ring (16) comprising a thread suitable for engaging with a thread (133) of the second electrode of one end of a second section (11b).</p> |
