井中地震震源———环形振动器已成功地用于裂缝型玄武岩含水层的井间地震勘探。这种地震震源采用离心质量旋转地震能量 ,在每个震源点记录下顺时针转动和逆时针转动所产生的扫描信号。由于该震源产生的是环形极化波 ,可以通过唯一的处理算法 ,将记录分解成两个等同而相互垂直的线性振荡地震源波。这样环形振动器就同时产生全方位角的P波和S波。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。在野外实践中 ,使用流体耦合的水听器 (也叫海底丰———译者注 )检波器来记录P波和S波。处理后的野外资料显示 ,从主测线和联络测线分量中分别分离出清晰的P波和S波。分解处理的张量卷积方法还用于多分量处理。
Well in the earthquake source --- ring vibrator has been successfully used for fractured basalt aquifer cross-well seismic exploration. The seismic source uses centrifugal mass to rotate the seismic energy and records at each source a sweep of clockwise and counterclockwise rotation. Because this source produces a ring-shaped polarized wave, the recording can be decomposed into two equivalent and perpendicularly-linear, oscillating seismic source waves by a single processing algorithm. This ring vibrator at the same time produce full azimuth P wave and S wave. P wave particle vibration coordinate rotation, can make different depth of the source component alignment. In the field practice, fluid-coupled hydrophone (also known as translator’s note) detector to record P-wave and S-wave. The processed field data show that the clear P and S waves are separated from the main and contact line components, respectively. The tiled convolution method for decomposition processing is also used for multi-component processing.
