【摘要】 针对老油区抽油机、高速公路等生产设施容易对野外地震勘探造成噪音干扰的现象,研究了抽油机噪音的产生机理和频谱特征,据此对压制方法进行了深入研究,提出了在地震施工过程中应用三维矢量组合压制抽油机噪音的方法。根据该理论设计了多种组合图形并分析了不同组合压噪效果差异的原因,通过对比压噪效果优选了最佳组合图形,实际的应用效果证明了三维矢量组合方法能够有效地压制抽油机形成的噪音污染。更多还原

【Abstract】 In response to the noise interference of field seismic exploration caused by the production facility such as pumping unit,joint stations and so on in the oil production areas,the noise source mechanism and frequency spectrum feature of pumping unit was firstly studied herein.Then,the suppress method was further studied to provide the approach to suppress pumping unit noise by three dimension vector combination in field seismic work.Based on this theory,many kinds of combination figures were designed,and the perform-ance of these combinations are also analyzed herein.The optimum figures are selected according to the comparison of different noise suppressing results.It is shown that the three-dimensional vector combination method can suppress effectively the noise pollution from pumping unit by the actual field application.更多还原
