Mathematical modeling of high-viscosity index oil formation with a sonic field at various frequencies

The paper describes the process of acoustic wave absorption in the oil-saturated porous medium in the case of cylindrical wave propagation. Terms of thermal and viscous-inertial absorption are introduced; the total attenuation ratio of the acoustic waves is calculated for various sonic field frequencies. The expression for sonic field thermal sources previously developed by the author is used to present the graphs of heat source distribution through the deposit in the cylindrical system of coordinates. The paper also considers a combination of the sonic field with a high-frequency electromagnetic field and some cross effects accompanying such a combination. Thus, it has been discovered that the energy of the sonic field is converted into heat in a closer near field of the deposit as compared to the electromagnetic field. At that, increasing frequency of the field leads to increased absorption zone in the radial direction.
