摘要
以经典的自由气泡振荡理论为基础 ,重点剖析了国外两种最具代表性的气枪子波理论模型。通过大量的实例计算和分析论证 ,并结合气枪子波实测资料 ,在旧模型的基础上提出了气枪理论子波修正数学模型。将修正模型用于实例计算 ,所得理论计算结果与实测子波非常接近 ,从而验证了修正模型的可靠性。利用计算的理论子波可以进一步作气枪阵列优化分析 ,这为现场的气枪阵列设计提供了参考依据。
The development of air guns has an important effect on marine seismic high-resolution surveys. Two typical mathematic models developed abroad for calculating the pressure waveform of an air gun were discussed on the basis of free bubble oscillation theory. A modified model was concluded and used to calculate the pressure waveform from an air gun and to correct the theoretical waveform. The exemplifications show that the result obtained from the modified model coincides much better with the actual waveform. The calculated waveform may be useful to the design of air gun array source.
