模糊聚类分析方法在地震层位自动对比中的应用

THE APPLICATION OF AMBIGUOUS CLUSTERING ANALYSIS TO SEISMIC HORIZON AUTOMATIC CONTRAST

本文探讨了模糊聚类分析方法在地震层位的自动对比中的应用,详细地分析了地震剖面所具有的模糊性质,提出了用模糊聚类方法在计算机上实现自动对比层位的流程,指出了在模糊聚类分析中用综合评判准则的必要性及其实现方法。文中对理论和实际剖面进行了计算,取得了较好的性质相近的样点的聚类,说明了模糊聚类分析方法在地震层位自动对比中的可行性。

This paper deals with the application of Ambiguous Clustering Analysis Technique ( ACAT ) . A detailed analysis is made with respect to the ambiguity of seismic section. The process of implementing horizon au-tocontrast on computer is presented. And the necessity of using the criteria of overall judgement while performing ACAT and the specific way to realize them are demonstrated. By using the calculus proposed in the paper to calculate theoretical and actual section, fairly good clustering with similar sampling poinst is achieved. The feasibility of performing the horizon auto-contrast using ACAC is remarked.
