摘　　要：在海洋油气勘探中,震源子波的优劣对地震勘探的效果有着至关重要的影响,如果气枪阵列未按照设计的参数进行激发,会严重影响地震资料的质量,所以对气枪阵列近场子波的质量控制是海洋地震采集中相当重要的一个环节。本文通过改造野外地震勘探船的网络结构,提出并实现了近场数据的实时传输和实时质控处理,避免了以往只能在地震作业完成后才能进行震源质控的缺点,提高了近场子波质控的时效性。最后通过对野外实际作业的案例分析,论证了实时质控的意义及有效性。In ocean oil and gas exploration,the superiority of source sub waves has a crucial impact on the performance of seismic exploration,and if the gas gun array is not excited according to the designed parameters,it can seriously affect the quality of seismic data,so the quality control of the gas gun array near-field sub waves is a rather important part of ocean seismic collection.By reforming the network structure of the seismic exploration ship,this paper proposes and realizes the real-time transmission of near-field data and real-time quality control processing,avoids the shortcoming that the source quality control can only be carried out after the completion of seismic acquisition operations,and improves the timeliness of near-field wavelet quality control.Finally,the significance and effectiveness of real-time quality control are demonstrated through the case analysis of field operation.
