FIELD: oil production, particularly enhanced recovery methods for obtaining hydrocarbons.
SUBSTANCE: method involves applying vibration action to well bottom zone from day surface and to casing pipes used as waveguide. One or several vibroexciters are installed under the casing pipes so that vibroexciter heads directly face casing pipe. The vibrations are excited by applying action to outer surface of overground casing pipe section through acoustically coherent unloading panel. Vibration action frequency is selected so that casing pipe length is equal to multiple half wave lengths. Casing pipe perforation zone is in wave crest area. Vibration action frequency is primarily estimated from analytic formula.
EFFECT: increased oil output and reduced water content in produced oil.
