method comprises the steps of lowering a vibroacoustic downhole emitter into a well down to a production layer depth and performing acoustic impact on the formation the impact is implemented by a multiple frequency signal containing at least two simple harmonic components whose frequencies and amplitudes meet the resonance overlapping condition application_number US 96438107 A description in accordance with the suggested method for enhancing oil recovery in a well to be subjected to an acoustic treatment a vibroacoustic downhole emitter is lowered into the well down to the production layer depth and it impacts the formation by a multiple frequency signal that contains at least two simple harmonic components whose frequencies and amplitudes meet the resonance overlapping condition it is also possible to implement the impact using a multiple frequency wide band signal with a continuous frequency spectrum the impact can be performed before starting oil production to clean pore space in adjacent area during oil production to increase fluid yield and while shutting a well to keep permeability level a physical mechanism the suggested method is based on calls for the application of fluctuation dissipation correlations for formation fluids the acoustic impact by a multiple frequency signal which contains at least two simple harmonic components whose frequencies and amplitudes meet the resonance overlapping condition as well as impact by a multiple.
