| 摘 要： | 在海洋地震勘探中,气枪组合震源得到广泛应用.目前气枪组合震源通常是采用模拟技术,得到震源的远场子波后,通过评价远场子波的参数来评价震源的性能.文章对气枪组合震源性能评价标准进行了简单叙述,对采用震源模拟软件模拟一系列震源进行评价后,优选了3 000 CI,并应用于实际地震勘探中,达到勘探地质目的,取得了良好的资料.

| Abstract: | The air gun array seismic source has been widely used in offshore seismic exploration. Nowadays the atr gun source 1s often evaluated by numerical simulation technique. After getting the far-field seismic wavelet, the performance of air gun source is evaluated by evaluating the parameters of the far-field seismic wavelet. The evaluation criteria on the performance of air gun array source have been discussed in this paper. Through evaluation on many air gun seismic sources with ntmaerical simulation software, 3 000 CI air gun seismic source is considered best in these seismic sources, and was put into use in real seismic data acquisition. The geologic exploration purposes have been reached, and quality of seismic data is excellent. |
