Fractured formations show very strong azimuthalanisotropy, causing great difficulties in exploration.
裂缝性地层表现出很强的各向异性，勘探难度很大。

For azimuthalanisotropy seismic exploration, it is very important to separate the fast and slow shear waves splitting in this type of anisotropic media.
在各向异性地震波勘探中分离快、慢横波技术是关键环节。

The maximum azimuthalanisotropy inferred from the azimuthal distribution method is decreased by about 30% because of dispersion of the azimuthal Angle of the reaction plane.
