FIELD: mining industry, particularly to rework production well, for instance to stimulate reservoir fluid influx.
SUBSTANCE: method involves immersing weight connected to suspension means in pipe string filled with liquid; exciting oscillations in well liquid due to weight moving. The weight is arranged in lower part of pumping unit stem, which is used as the resilient suspension means. Load is made as a piston and comprises coaxially arranged wheels with blades extending at an angle to vertical axis. This provides bringing the wheels into rotation during pumping unit operation to convert axial weight movement into vertical and horizontal liquid oscillation with frequency depending on speed of weight movement in the liquid.
EFFECT: possibility to perform vibratory-and-wave treatment of well bottom zone provided with pumping unit within wide frequency range.
