Work is directed on increase of efficiency of acoustic influence on well bottom zone for in-crease in oil recovery of a layer. On the basis of the researches spent by authors it is shown that the account of features of distribution of sound fluctuations in the punched chink and a choice of a mode of acoustic influence allows to reduce losses of energy of elastic waves considerably. Processes of distribution of elastic fluctuations in a chink and their transfers through punched apertures in environment are investigated. Settlement formulas for definition of frequency of own fluctuations and good quality in the punched pipe are received. Conditions of maintenance of a resonant mode are defined.
