摘　　要：应用于海洋地震勘探的气枪阵列是采用气枪相干组合理论设计而成的。有关阵列的激发能量、工作性能的主要评价指标为远场子波特性及频谱图。为了评价阵列的工作性能,就必须对其远场信号进行测试。本文较详细地介绍了SEG海洋地震震源测试标准中有关测试的基本条件、设备、关键方法及数据处理技术。Air gun array used to acquire geophysical exploration seismic data in off-shore is designed on the basis of interacting theory. The attributes of wavelet that radiates to far field and the spectrum are the primary focus of testing standard about the energy and working performance of air gun array, and first of all, the far-field signal must be tested. This article introduced the basic testing condition, equipment, methods and data processing technology on testing standard of SEG marine seismic air gun.
