地震勘探中至今还没有实际应用横波。本文说明与处理工作有关的日常地震工作中横波观测的可能性。横波的重要性在于:①获得额外的速度信息,②有助于岩性参数的确定,③确定及鉴別某种形式的噪声能量,④讨论由于温度效应引起的弹性参数的变化。横波垂直时距曲线与地震测井的结果以及由纵波记录得到的垂直吋距曲线的比较,符合得很好。用三分量检波器记录时,发现横波的反射时间直至大约4秒。
There is no practical shear wave in seismic exploration so far. This article explains the possibility of transverse wave observations in routine seismic work related to handling. The importance of shear waves lies in: (1) obtaining additional velocity information; (2) contributing to lithologic parameters; (3) identifying and identifying some form of noise energy; and (4) discussing changes in elastic parameters due to temperature effects. The results of the vertical shear-time curve of shear-wave and seismic logging and the comparison of the vertical distance curve recorded by the longitudinal wave records are in good agreement. When recorded with a three-component detector, the reflection time of the transverse wave was found to be about 4 seconds.
