D-S证据理论在地震属性中的应用
摘要
Abstract
Evidence theory is widely used in data fusion systems. However, it is never used in seismic at-tributes analysis. A new application of D-S evidence theory in seismic attribute is presented. The process of the D-S information fusion method contains the following steps; firstly, using the complex seismic trace analysis to extract three instantaneous attributes (instantaneous amplitude, instantaneous phase and instantaneous frequency) ; then, utilizing the modified D-S algorithm on the combination of three instantaneous attributes and getting the final result of the data fusion system; finally, effectively combination of the useful information of the three seismic attributes which reflects more clear local changes of seismic signals than single attribute. The actual example shows D-S information fusion method brings better reflections on changes of seismic properties, geological phenomenon and geological deposition.关键词
