摘要The large volume air-gun sources have been successfully applied in onshore-offshore seismic experiments in northern South China Sea, and in a reservoir located in Hebei Province. The permanent stations can receive the seismic signals from the air-gun sources as far as 255 km away. The seismic waveform characters are easily identified comparing with the waveforms of natural earthquake and explosion of similar magnitude. The air-gun signals usually have 4 similar to 8 Hz dominant frequency, 3 similar to 5 wave peaks, +/- 0.15 mu m . s(-1) amplitude, and distributed at regular time-intervals. And this kind of air-gun sources have many advantages, such as high energy, high repeatability of firing, high S/N ratio, and environmental protection. The above characters indicate that the new 1500 LL air-gun sources are very suitable for studying continental and oceanic crustal structures.
