摘要
抽油机作为老油区地震资料采集中遇到的主要干扰之一,对于地震资料的信噪比有较大的影响。针对这一现象,研究了抽油机噪音的周期性特征,提出了波场信号重构压制周期性噪音的方法。利用噪音的周期性,从不同角度对噪音进行消除,达到去噪的效果。
The pumping unit, one of the main interference encountered in the acquisition of seismic data in the oldoilfield, have a great influence on the signal-to-noise ratio of the seismic data. Aimed at resolving the problem, thecharacteristics of the cyclic noise of the pumping unit are researched. It is proposed that the cyclic noise issuppressed by reconstructing the wave field signal. The noises are removed from different angles by using thecyclicity of the noise.
