Wavefield separation is one critical step in the three-component (3C) vertical seismic profiling (VSP) data processing. The conventional 3C VSP wavefield separation method exhibits low precision polarization angle and cannot obtain desirable results. This letter proposed the right-hand rule 3C VSP wavefield separation method which has many advantages over the conventional 3C VSP wavefield separation method—particularly the polarization angle precision and wavefields continuity. Analysis of real 3C VSP data demonstrates that the right-hand rule 3C VSP wavefield separation method can enhance polarization angle precision and show a very desirable ability to produce high-continuity wavefields.

右手定则 3C VSP 波场分离法

波场分离是三分量 (3C) 垂直地震剖面 (VSP) 数据处理中的关键步骤之一。传统的3C VSP波场分离方法偏振角精度低，无法获得理想的结果。这封信提出了右手定则3C VSP波场分离方法，它比传统的3C VSP波场分离方法有很多优点——特别是偏振角精度和波场连续性。对真实3C VSP数据的分析表明，右手定则3C VSP波场分离方法可以提高偏振角精度，并显示出非常理想的产生高连续性波场的能力。
