Abstract:
In this paper, the characteristics of noise generated by a gas flow in samples of porous media are investigated. It is shown that the dependence of the maximum of the sound intensity on the filtration rate is quadratic, which means a linear dependence of the amplitude of the sound oscillations on the filtration rate. It is also shown that, at the same filtration speed, the sound intensity will be greater for those samples that have less permeability and porosity. The obtained results can be used in the formation of the theory of filtration sound formation, as well as in the interpretation of data recorded by a downhole sound level meter when conducting well logging.
