dipole shear wave FMI log 极横波成像测井
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。
