摘要
传统上,采集地震资料基于这样的假定:检波器的质量要尽可能地小。1999年,当Steeples和其合作者使用一个农场耕作工具,将72个检波器自动、并几乎同时地进行了插置时,每个检波器的有效质量有了显著的提高。通过在100Hz的垂直检波器的顶部施加不同的重量,对检波器的质量如何影响传播时间、振幅、频率及资料总的品质进行了试验。在资料的采集过程中,还对能提供不同能量的四种震源进行了测试。对试验得到的资料进行频谱分析显示,较小的重量对检波器记录地面震动的能力影响最大,很大的重量对检波器记录地面震动能力的影响却有限。
The weight of geophone is assumed to be too little to take into count for seismic data acquisition traditionally. 1999, Mr. Steeples and his partners used farm - tools to plug 72 geophones almost in the same time, their experiment proved that effect weight of each geophone seemed to greatly arise in this way. Other experiments are made to test the influence of geophone weight on the transmission time, amplitude, frequency and data quality by applying different pressure vertically on the top of 100Hz geophone. Meanwhile, they also tested the energy of each of four kinds vibrator. Materials acquired by the above mentioned experiments showed that: the lighter the geophone is, the better the data quality will be gained.
