【摘要】 当信号和噪声差异较小且难以区分时,数字滤波方法的应用势必受到限制。为此,本文尝试利用地震波形态的差异,借用在数学形态学基础上发展起来的形态滤波方法压制地震记录中的野值脉冲噪声。文中主要讨论了形态滤波方法的基础理论,并探讨了形态滤波中结构元素的尺寸、形状对处理结果的影响,并对实际地震资料做了试处理,获得了较好的应用效果。鉴于数学形态学用于地震资料处理是一个新的应用领域,希望能有更多的人加入这一领域的研究。更多还原

【Abstract】 The application of digital filtering method has to be limited when the signals and noises are difficult to be separated. For that reason, the paper tried to use the difference in shape of seismic wave and morphologic filtering method developed on the basis of mathematic morphology to suppress the accident pulse noises on the seismic records. The basic theory of morphologic filtering method was mainly discussed in the paper,the size of structural elements and effect of shape on the processing results were also probed. The test processing of real seismic data was conducted. which achieved good application effects. In view of that using mathematical morphology for seismic data processing is new application realm,we hope that there are more persons can joint the studying ranks.更多还原
