摘    要:本文基于地震剖面的数字化图像特征,提出用光栅算子将地震剖面按产状分离成产状相对单一的多幅数字图像剖面。对每一幅产状相对单一的数字图像剖面,用向量分解技术的向量最大特征值对应基向量投影的原理获取有效相干信息的办法实现信噪分离;在结合地质、物探分析的基础上进行最终输出剖面的滤波加权重建,获得信噪比高、波组特征保持好、分辨率相对保证的剖面。实际资料处理结果表明本文提出方法的去噪应用效果显著。

关 键 词:地震剖面  数字化图像  向量分解  滤波加权

Abstract:This paper introduces an image processing technique into seismic data processing as a noise attenuation technology. The image separation of the seismic profile is obtained by using grating operators based on different time dips and a set of relative single dip profiles is obtained. A high signal to noise ratio profile can be obtained during reconstruction by statistical weighting. With further processing analysis and geological study, a high signal to noise profile that can meet geological requirements can be produced. The real data examples show that the signal to noise ratio of the profile is greatly improved, the resolution of the profile is maintained, and the fault terminations are much clearer after using the image processing method.
Keywords:seismic profile  digital image  and vector decomposition
