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。
In view of the fact that production facilities such as pumping units and expressways in the old oil area are prone to cause noise interference with field seismic exploration, the generation mechanism and spectral characteristics of the pumping unit noise are studied. Based on this, the suppression method is studied in depth. Application of 3D Vector Combination to Suppress Noise of Pumping Unit in Earthquake Construction. According to the theory, a variety of combination patterns are designed and the reasons for the difference in the effects of different combinations of noise are analyzed. The best combination of patterns is selected by comparing the effects of noise and noise. The practical application shows that the three-dimensional vector combination method can effectively suppress the pumping unit The formation of noise pollution.
