Badanie wpływu anizotropii i zailenia na prędkości rozchodzenia się fal podłużnych i poprzecznych oraz innych parametrów sprężystych skał klastycznych

Abstract

Rock anisotropy has a significant effect on longitudinal and shear wave velocities, that are measured in acoustic logging. This can affect both a single layer (then it is related to the microstucture) and a sequence of layers (a large scale). This paper discusses elastic components of anisotropic media with so-called transverse isotropy (TI) and Thomsen coefficients characterizing the P-wave and S-wave anisotropy and $V_{P}/V_{S}$ ratio. The effect of shale rock content on parameters measured in acoustic logging was also studied.
