fast and slow S-wave 快慢横波
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 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。
Reflection energy is extracted from the split fast and slow S wave components, and then imagery processing is carried out for it using VSP-CDP transform method.
从分离的快横波分量中提取反射能量，然后用VSP-CDP变换方法作成像处理。
