Zusammenfassung:FIELD: mining industry, particularly to rework production well, namely to stimulate reservoir fluid inflow. ^ SUBSTANCE: method involves arranging hammer connected to suspension means inside pipe string filled with liquid; exciting periodical oscillations by axial hammer movement, wherein hammer movement speed is chosen to provide necessary force of hammer impact upon pipe string walls; installing sucker-rod pump in the well; connecting sucker-rod pump plunger with hammer arranged below it through resilient suspension means; exciting periodical liquid oscillations by transfer of sucker-rod pump plunger movement energy to the hammer. Hammer mass and resilient suspension means rigidity is selected to provide hammer movement amplitude and speed higher than that of the plunger. ^ EFFECT: possibility of wave treatment of well bottom zone during well operation without well suspending. ^ 1 dwg
