Abstract
Oil recovery enhancement method that calls for lowering a vibroacoustic downhole emitter into a well down to the production layer depth and for performing acoustic impact on the formation, wherein the impact on the formation is implemented by a multiple frequency signal containing at least two simple harmonic components whose frequencies and amplitudes meet the resonance overlapping condition.
