Study of the influence of the frequency of the wave action on oil production

The paper investigates the change in the parameters of rocks and oil production at different frequencies of wave action. Wave action technologies are divided into two groups: with a frequency of less than ۱۰۰ Hz and a frequency of more than ۱ kHz. In the intermediate area, no implemented activities and studies on wave action were found. For low-frequency impact, an increase in permeability values is noted to a greater extent due to the appearance of new and an increase in the size of existing fractures. With high-frequency exposure, the viscosity of reservoir oil is greatly reduced. The greater the value of the initial viscosity, the more intensively it decreases under high-frequency wave action. For the Perm region the results of wave treatment of production wells were compared depending on the frequency of exposure. With an increase in the frequency of exposure, the average results of wave processing decrease. Models have been obtained to predict the time of well operation with additional oil production, additional oil production and an increase in oil production rate of wells after wave action.
