| 摘 要： | 记录中的猝发脉冲、漏电感应及50Hz工业频率干扰等异常噪声具有能量和频率异常、出现位置不规则及分布随机的特点，是叠前数据中普遍存在的噪声。通过理论和实际数据的分析表明，异常噪声对叠前多道处理（如地表一致性振幅及叠前随机噪音衰减等）的影响不容忽视，精细的叠前数据分析和有效的异常噪声压制是提高数据处理质量的保障。

| Abstract: | The abnormal noises, such as burst pulse, electricity inflection, and interference of 50Hz industrial frequency, are common in prestack seismic data. Their energy, frequencies, and dispositions are different from that of seismic signals. This paper illustrates with both synthetic and real data that the impact of the abnormal noises to prestack multichannel processing can not be ignored. It is necessary to do detailed analysis on prestack data and perform effective noise suppression to guarantee the quality of data processing. |

| Keywords: | abnormal noise S/N ratio multichannel processing surface consistent processing amplitude compensation random noise attenuation |
