Effect of Parameters of Liquids on Amplitudes of Pressure Waves Generated by Electric Discharge

Resumo

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.
