Abstract. Annotation. The research paper provides the review of calculation methods enabling to determine parameters of pressure wave at the electric discharge in water at a certain distance from the discharge channel. The variety of approaches used in scientific publications is considered: mathematical modeling, empirical and semi-empirical calculation models and expressions. Under initial conditions, which correspond to the parameters of electric discharge method of oil production intensification, value of the pressure wave amplitude calculated with the help of selected calculation techniques is compared with experimental evidence. It is noted that when the discharge circuit inductance is 4 μH, a good coincidence of the calculated and experimental data is observed. With a small inductance of the discharge circuit (0.9 μH), there is a discrepancy between the calculated results obtained with the help of certain techniques and the data obtained by physical experiment.
Keywords: Keywords: electrical discharge in the fluid, pressure wave, amplitude of pressure wave.
