FIELD: mining.
SUBSTANCE: device for wave action on productive stratum includes deep-well sucker-rod pump, flow column with filter and tail with rest upon bottom. In top half of tail it is mounted increased in weight component - solid metal cylinder or section of increased in weight tubes. At that there is fulfilled the condition lm/L<0.1, where lm- length of increased in weight component, m; L - well depth (distance from mouth till bottom), m.
EFFECT: decreasing of obtained production watering and increasing of productive stratums oil recovery.
