DEVICE FOR STIMULATION OF WELLS AND DIAGNOSTIC METHOD FOR SUCH A STIMULATION DEVICE

摘要

A device (20) for stimulation of wells, includes a tool (200) including a capacitive element (205) and a stimulation head (210). The device further includes switching elements capable of placing the tool (200) in at least two states: i) a charging state in which the capacitive element and the stimulation head are electrically in series between the first terminal and the second terminal of the tool, in such a way that the electrical source charges the capacitive element through the stimulation head (210), and ii) a discharging state in which the capacitive element discharges through the stimulation head (210). A diagnostic method for such a device (20) for stimulation of wells is also described.
