摘要:
分析比较4处不同形状水体气枪激发信号的主要特征,得到水体形状对气枪激发波形影响的关系,并利用数值方法模拟不同陆地水体中气枪激发的过程。研究结果表明:不同水体形状对气枪信号存在一定程度的影响,并且对高频信号成分影响较强,对低频信号成分影响较弱。在进行的4组实验中,马刨泉实验信号气枪能量转化为低频能量的效率高,所激发信号波形尖锐。
Abstract:
We analyzed the data of four airgun experiments in different water shapes to obtain the influence relation-ship of different water shapes on wavefrom of airgun and carried out corresponding numerical simulations to simulate the process of airgun exciting in different water shapes.We find that water shape has an influence on airgun triggered signals.The influence on high frequency is strong but on low frequency is weak.Among our four experiments,the MPQ Pool experiment has highest energy transform efficiency and a sharp waveform.
