摘要
气枪阵列作为震源具有很多优点,在海上地震勘探领域应用已久。国内对气枪的理论研究不多,认识不足。本文探讨了国际上主要的几种气枪单枪理论模型,同时对于气枪相干特性进行了较为深入的研究,提出了气枪阵列子波的算法。结合现场实际资料,进行了对比和验证,得到了较为接近实际情况的结果。
As a source,the air-gun array has many advantages and has been used in marine seismic exploration for a long time. The theoretical study of air-gun is rare at home and the importance of air-gun is lack of knowledge. The paper probed the theoretical models of single gun for several major air-guns abroad,deeply studied coherent characters of air-gun at the same time, presented the algorithm of air-gun array wavelet. The tests has been done in comparison with real field data, which showed that the modeled results are more close to the actual data.
