【摘要】 海洋地震资料采集中空气枪震源近场检波器不仅可以较好地进行震源质量实时监控,更重要的是可以较好地预测远场子波.经国外大量的远场子波实测试验与预测结果对比,利用近场检波器预测远场子波,与实测远场子波吻合度很高,因此,利用近场检波器预测远场子波是一项非常关键的技术,然而国内在该技术领域还不是很成熟,目前只用来做一些震源的质量监控和近场子波记录.较为详细地描述了国外的部分试验结果,并根据国外的试验结果和国内的具体使用情况,提出了近场检波器放置位置、记录长度和采样率合理化选取的建议.并建议国内相关领域的专家尽快研发拥有自主知识产权的相关软件,利用近场子波来有效地预测远场子波.更多还原

【Abstract】 The near field hydrophone can do well at quality control of air-gun source in marine seismic data acquisition,and the more important function of the near field hydrophone is to predict the far-field wavelet.Through a large quantity of foreign literature recording,the predicted far-field wavelet by near field hydrophone is almost same as measured far-field wavelet.So it is a key technology that predicting the far-field wavelet by near field hydrophone,but this technology is not extensive developed in our country,only use it’s apart of function to control the quality of the air-gun source and recording the data.The paper discussed some foreign test result,and put forward some advice according these successful test result and the application situation of near field hydrophone in our country,these advic included how to place the near field hydrophone and how to choose the record length and sampling rate.Of course,it suggested internal experts should research and develop the independent intellectual property right software about near field hydrophone,so we can predict the far-field wavelet efficiently by near-field wavelet.更多还原
