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。
Traditionally, the acquisition of seismic data is based on the assumption that the detector should be as small as possible. In 1999, when Steeples and his collaborators used a farm-farming tool to automatically place 72 geophones and insert them almost simultaneously, the effective mass of each geophone was significantly increased. By applying different weights on top of the 100Hz vertical detector, experiments were conducted on how the detector’s quality affects the propagation time, amplitude, frequency, and overall quality of the data. During the acquisition of the data, four sources were also tested for different energies. Spectrum analysis of the data obtained from the experiments shows that the smaller weight has the greatest effect on the capability of the geophone to record the ground vibration. The great weight has a limited impact on the geophone’s ability to record ground vibration.
