Abstract
An experimental study is performed on the effect of hydrostatic pressure, temperature and specific electric conductivity of a liquid on the amplitude of a pressure wave generated by an electric discharge in a liquid during the electric discharge treatment of oil wells. The results show that with an increase in 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 a specific conductivity of the produced water) decreases (up to 67%) the amplitude of the pressure wave. During the treatment of the oil wells using the electric discharge immersion device, it is necessary to use a scheme with a closed electrode system, since in this case the treatment efficiency is independent of the electric conductivity of the downhole fluid.
