Abstract
An electrode system of device for electrohydraulic action on the bed contains a positive electrode, a negative electrode concentrically installed relative to it and an insulator dividing electrodes. On the external surface of positive electrode a dielectric coating is applied, on external surface of which spiral groove and through channel in the form of a cut along the groove are made. The invention relates to the oil-producing industry, electrohydraulic devices used at excitation of bore holes.
