The main parameters of shear-wave splitting are respectively polarization of fast shear-wave, and time delay of slow shear-wave.
快剪切波偏振方向与慢剪切波时间延迟是描述地震各向异性的两个主要参数。
Fast shear wave is obviously different from slow shear wave in amplitude and frequency characteristics.
同时快横渡与慢横波在振幅和频率特征上也具有明显差异。
Since P-Wave can not be suppressed in dipole shear wave log in slow formation, there are some difficulties in picking the first S-Wave arrival.
在慢速地层中偶极横波测井不能很好地压制纵波，致使横波首波的检测存在一定的难度。
The attenuation factor of longitudinal wave was changing linearly, whereas the attenuation factor of the slow shear wave kept nearly constant with a low frequency on the exploration seismic band.
纵波的衰减系数在地震频带内基本上呈线性变化，而横波的衰减系数在地震频带内除低频外基本保持稳定。
The results show that the method can skip over the P-Wave and exactly pick the first S-Wave arrival in dipole shear wave log in slow formation.
实际资料处理结果表明，该方法可以跳过慢速地层中偶极横波测井的纵波而检测横波初至。
Then the azimuth of formation fractures is estimated; and with the joint use of zero offset P wave source VSP data, fast and slow shear wave seismograms are obtained to have fracture density.
在获得地下裂隙方位角的同时，结合零偏纵波VSP资料得到快、慢S波记录，进而计算了裂隙密度。
