In our current research, we put forward the performance of attenuation caused by interlayer flow of layers whose reflection coefficient is related to frequency (Bai et al., 1975). Quintal, etc. (2009) shows that the physical parameters of real sandstone reservoirs related to water and partially unsaturated polyester resin and quality factor (wave attenuation can be defined as Q- 1) are very wide, which can be similar to the interlayer flow model. Their inter-application flow model studies the reflection coefficient [j]. This layer is thinner than the wavelength of light and partially saturated with water and gas, showing such high attenuation. The amplitude reflection coefficient of a layer can be greater than 10% and less than 4. Q Because of the non-attenuation in this background, there is no acoustic (real) impedance. In this paper, we also consider the influence of boundary layer thickness on amplitude reflection coefficient in Quintal et al. (2009). The frequency-dependent elastic layers of reflection coefficient are the top and bottom layers reflected by constructive and destructive interference waves (for example, Kallweit and Wood, 1982). This effect refers to tuning. The reflection coefficient and frequency-dependent attenuation of a layer are dominated by two frequency-dependent mechanisms: the layer that adjusts and attenuates the reflection coefficient has the largest transition and the frequency when it is adjusted is the same. The frequency attenuation is the largest at the transition frequency; However, when the tuning frequency occurs in positive and negative interference, the reflected wave with maximum amplitude is generated. Here we know that compared with the background, the attenuation of the layer and the adjusted reflection coefficient will show extremely high attenuation, but there is no impedance contrast. In order to study the frequency-dependent attenuation and adjusted reflectivity, we use: (1) to solve the interlayer flow model (Bai et al.,1975; Carcione and Picotti, 2006), the influence of frequency-dependent attenuation; (2) The reflection coefficient (Brekhovskikh, 1980) of one-dimensional analytical solution is embedded in elastic medium to simulate and tune the influence of different layer thickness and wavelength.
