Abstract. The work presents methods for calculation of parameters of the pressure wave gener-ated by electrical discharge in the fluid in the rock at a given distance from the source of distur-bance. With the help of these methods and experimentally obtained pressure wave profile, numeri-cal study of the wave distribution in the face area of the well treated by the electric-discharge me-thod of decolmatation was carried out. The results of the study showed that during the electric-discharge decolmatation not only the wall of the well and the perforations were affected, but also the bottom zone portion which was nearest to the well bore. Despite of the fact of complete attenua-tion of the pressure wave in areas nearest to the face area, the obtained results allow making a con-clusion about expediency of the electric-discharge effect application for treating the oil wells in or-der to increase their flow rate.

Keywords: electric discharge in fluid, pressure wave, attenuation factor, rocks.
