The invention relates to pulse equipment that is used in oil-producing and water-producing industry, in particular for cleaning perforation zones and well filters at extraction of liquid and gaseous products. An electrode system of the device for electro-hydraulic bed stimulation has positive electrode placed in fluid working medium, negative electrode installed concentrically with respect to it, this is body of the device, and flow-through and support insulators that separate electrodes. According to the invention it is equipped with intermediate electrode arranged as disc with sharp edge fixed horizontally on support insulator and insulated from above. And support insulator is installed with possibility of axial displacement and has cavity inside it, this is filled with dielectric, there coil winded on ferromagnetic core is placed, its upper end is connected to intermediate electrode and the lower one – to negative electrode. The system makes it possible to achieve increase of inter-electrode gap to optimal value and due to that to achieve largest value of hydro-dynamical pressure on near zone of the bed, this is formed by vapor-gas cavity that is brought about due to electric discharge. |
