三维地震勘探抽油机噪声特征分析
|
摘要
老油区经过多年的勘探开发,其周围的勘探环境变得较为复杂,主要是增加了许多机械设施,尤以抽油机的机械振动对地震勘探的影响最大。针对这种情况,本文着重对抽油机产生的噪声干扰特征进行了详细分析,对不同接收组合排列获取的数据从传播特征和空间特征两方面进行了几何学特征分析,从振幅能量特征、频率特征和相位特征等方面对抽油机产生的噪声干扰进行了动力学特征分析。以上分析对研究相应的噪声压制方法具有一定的指导意义。
After many years' exploration and development,the exploration environment around the maturing field became complicated,the reason is mainly increasing many mechanic equipments,especially the pumping units,the mechanic vibration of which has larger impact on seismic exploration.Facing with the situation,the paper emphatically analyzed in detail the feature of noise interference produced by pumping unit,analyzing the geometric feature from two aspects of propagating and spatial feature and analyzing the dynamic feature of noise interference of pumping unit from the aspects of amplitude,frequency and phase feature for the data acquired from the spreads with different receiving array.The above analyses have some guiding meaning for studying the corresponding noise-suppressed method.
