Three-component VSP data of P-wave source are applied to fracture detection.
本文利用P波源三分量vsp资料进行裂缝检测。
Using coordinate rotation based on P-wave particle vibration, aligning the source components at different depths have been achieved.
采用P波粒子振动的坐标旋转，可使不同深度的震源分量对齐。
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。
The results show that within the limit of these existing equipment source-receiver spacing range, there is be clearly observed P-P reflected wave in the full-wave waveform.
结果表明，在现有仪器源距范围内，可以从全波波形中观测到清晰的反射纵波。
