摘要
Based on the principle of seismic structural properties,the authors elaborate in this paper the definition and characteristics of grey level co-occurrence matrix (GLCM),and propose calculation methods of seismic structural properties.Then the authors convert images of seismic wave to chromatic difference images with clear geological meanings(energy,entropy,contrast and homogeneity) to identify complex geological units.The application in west slope of Damintun Sag shows that faults can be identified by the contrast attribute,and lithological sedimentary bodies can be recognized by the entropy attribute.All this interpretation coincides very well with the drilling data.So the seismic structural properties analysis can be used in a joint interpretation as an approach to identify fault systems and lithological sedimentary units.
