| 摘 要： | 用单孔检层法测定山西临汾流动地震观测台址两个钻孔的P／S波速度结构，为研究地震观测台址速度结构对地震波接收效果的影响提供基础资料。与常规P／S波测井不同的是，在P波速度测试中采用高频24道水听器串共炮点接收，有效降低单点多炮接收因重复性问题带来的零时误差，提高P波速度测定的精度。该方法可为类似工程场址的高精度P／S波速度测试提供新途径。

| Abstract: | Using the single-hole layer detection method, the P/S wave velocity structure of two drillings, which are located in Linfen, Shanxi Province, are determined, to obtain the basic information for the study on the influence of the velocity structure of temporary seismic observation site to seismic wave receiving effect. Compared to conventional P/S wave velocity logging, the difference of this method is that we used high frequency 24-level vertical hydrophone array receiving seismic waves, effectively reduced zero error result from the problems for receiving repetitive of the single point and multi-sources, greatly improving the accuracy of the P-wave velocity testing. This method can he used as a new method in the similar project of high precision P/S wave velocity test. |
