摘要：

柴北缘地区由于受复杂地表条件和地下构造的影响，存在多种类型干扰波，山前和构造顶部地震资料信噪比低。通过对柴北缘平台地区、马海地区和冷湖地区地质条件及地震资料的综合分析，加深了对柴北缘地区干扰波类型和参数特征的认识，并根据干扰波分析结果，提出了相应的压制方法。

关键词: 干扰波类型, 干扰波特征, 地震地质条件, 去噪, 柴北缘

Abstract:

Due to the complex surface conditions and the impact of subsurface structure, there are many types of interference waves in the northern Qaidam basin. And signal/noise ratio of seismic data is low in foreland as well as in the top of structure. Through the comprehensive analysis of geological conditions and seismic data from Pingtai, Mahai and Lenghu regions in northern Qaidam basin, a deeper understanding of the type and parameter characteristics of interference wave has been made. With the result of analysis, corresponding method has been proposed to suppress these interference waves. This method will be helpful for noise attenuation more in northern Qiadam basin.

Key words: Type of interference wave, Characteristics of interference wave, Seismic geological conditions, Noise attenuation, Northern Qaidam basin.
