| 摘 要： | 地震勘探中50Hz工频干扰信号是所采集的地震资料中最强的一种有害信号,在后续资料处理中采用陷波方式消除50Hz信号时容易影响到有用信号。在采集过程中,采用平衡对地电容的方法,可以有效地降低50Hz工频干扰,平均噪声水平达20dB,能有效提高资料品质。

| Abstract: | 50Hz disturbance is the strongest harmful signal in seismic data. We usually notch 50Hz in data processing, but this harms the useful signal. This paper presents a simply design balancing capacitor to ground which can efficiently reduce 50Hz disturbance,with average noise level 20dB, and improve the data quality. |
