本文简要地介绍了海洋地震气枪震源试验所采用的测试方法和结果,分析了单枪与组合气枪声讯号的波形、振幅和频谱。各种容量的气枪组合,对抑制气泡效应有明显的效果,并可以增强声讯号主脉冲的声压,改善其频率特性,较好地满足海上地震勘探的需要。 This paper briefly introduces the test methods and results of the marine seismic airgun source test, and analyzes the waveform, amplitude and frequency spectrum of the single gun and combined air gun signals. Airsoft guns of various capacities have obvious effect on suppressing the bubble effect, and can enhance the sound pressure of the main pulse of the acoustic signal to improve its frequency characteristics and better meet the needs of marine seismic exploration.
