横波地震探测应用实例

S-WAVE SEISMIC DETECTION APPLICATION EXAMPLES

横波与纵波相比,具有速度低、频率低、波长短,且不受地下水影响的优点。因此横波地震勘探可以达到纵波地震勘探所无法达到的分辨率和精确度,能很好地完成对第四纪覆盖物及其下伏基岩探测的任务。这里以汉旺镇某地为例,介绍了横波地震在对浅层地区勘探的数据采集方法以及后期地震资料处理流程,结合相关资料,对浅层地层层面进行了划分,收到了较为理想的效果,从而得出了横波地震勘探技术具有实际可行性和良好的应用发展前景的结论。

S-wave,compared with P-wave,has low speed,low frequency,wave length,and is of the advantages of no groundwater impact.Therefore,the S-wave seismic exploration can reach high resolution and accuracy whist the P-wave seismic exploration can not.This feature of the S-seismic wave is well to detect the Quaternary covering underlying layered bedrock.The Hanwang example,describes the S-wave seismic data collection method and the latter shallow areas for exploration seismic data processing flow,combined with relevant information,were divided on the level of the shallow strata,received a more satisfactory results.The above study suggests that the S-wave seismic exploration techniques are practical feasibility and with a good application prospect.
