Propagation of acoustic wave and analysis of borehole acoustic field in porous medium of heterogeneous viscous fluid
نویسندگان
چکیده
Sound field in fluid-saturated porous medium is closely related to the viscosity of fluid and heterogeneity medium. In order improve physical mechanism wave propagation expand its application borehole acoustic field, shear stress pore structure are considered. The theory containing viscous deduced based on Biot theory. influence parameters slow analyzed, dispersion attenuation elastic caused by balance under inhomogeneous studied. analytical solution further derived. phase velocity mode waves heterogeneous medium, waveform full calculated. analyzed. results show that there fluid. characterized low large attenuation. process not only leads fast P-wave, but also affects characteristics pseudo Rayleigh Stoneley wave. addition, has a great present work improves provides theoretical guidance for explanation formations.

Acoustic Wave Propagation in and around a Fluid-filled Borehole of Irregular Cross-section
Boreholes with 10% or more ellipticity are not uncommon. In this paper, we consider the coupling of an incident elastic wave into a borehole of irregular cross-section and investigate the cross-mode coupling phenomenon in sonic well logging in the presence of borehole irregularity. The mode-matching method is used. Different from its original formulation, we employ the Reichel et al. algorithm ...
متن کاملAnalysis of Acoustic Wave Propagation in a Thin Moving Fluid
We study the propagation of acoustic waves in a uid that is contained in a thin two-dimensional tube, and that it is moving with a velocity pro le that only depends on the transversal coordinate of the tube. The governing equations are the Galbrun equations, or, equivalently, the linearized Euler equations. We analyze the approximate model that was recently derived by Bonnet-Bendhia, Duru é and...

A monopole or a dipole source in a fluid borehole generates acoustic waves, part of which propagate along the borehole and the other part enter the formation propagating as Por S-waves. The refracted waves propagating along the borehole wall are used to determine Pand S-wave velocities. However, a significant fraction of the seismic energy radiates into the formation. In this laboratory study, ...
