摘　　要：近场数据在海洋地震勘探震源质控中发挥着重要的作用,随着技术的进步,近场数据的质控方法也日趋完善。这里在介绍近场数据的来源及基本原理基础上,根据多年海上质控经验,系统总结了近场数据在采集质控中的应用实例,包括枪子阵同步性质控,单枪测试,枪漏气,枪自激等,并对应用效果进行了对应的分析。实际应用效果表明,通过对原始的近场数据进行不同的处理,可以更全面地质控震源,不同的质控方法均取得了很好的应用效果,保证了海洋地震数据的采集质量。Near-field data plays an important role in controlling of source quality of marine seismic exploration.With the development of technology,the quality control method of near-field data is becoming more and more consummate.Based on the introduction of the origin and basic principle of near-field data,the authors systematically summarized the application examples of near-field data in controlling of acquisition quality based on many years of experience about quality control,including synchronicity quality of sub-array,bubble test,gun leak,gun auto fire,etc.,and then analyzed the corresponding application effect.The practical application results show that the source can be more comprehensively for quality control through different processing of the original near-field data.Different methods on quality control have achieved good application effect,which ensure the quality of marine original seismic data.
