An experimental study of the effect of hydrostatic pressure, temperature and specific electrical conductivity of a liquid on the amplitude of a pressure wave generated by an electric discharge in a liquid during electric discharge treatment of oil wells is performed. The obtained results showed that with increasing hydrostatic pressure, the amplitude of the generated pressure wave decreases. The use of a fluid with a conductivity of 0.53 S/m as a working medium (which is close to the value of the specific conductivity of the produced water) leads to a decrease (up to 67%) in the amplitude of the pressure wave. Therefore, when processing oil wells using the electric discharge immersion device, it is necessary to use a treatment scheme with a closed electrode system, since in this case the processing efficiency does not depend on the electrical conductivity of the downhole fluid.
