Study on application method of edge detection attributes
Abstract
Some important informations of fault,fracture,lithology and facies change can be acquired through the interpretation of seismic attributes.This paper put forward edge detection attribute.The attribute is that new seismic attribute can be obtained by the processing of amplitude attribute through the using of edge detection method during image processing.The attribute can be applied for lithlology identification.Feasibility of the method in identifying boundary is verified through the verification of edge detection method with actual mathematical model to identify the boundary.Based on several classical edge detection methods and combined with actual seismic data,it is found that the Sobel attribute can reflect the image boundary.Sandstone and mudstone are distinguished on the basis of the verification of drilling data and well logging data.Application of new attribute can distinguish the boundary of sandstone and mudstone,can decrease the errors creased by the attribute subdivision,which has an important significance in improving sandbody identification precision and describing sandbody distribution.
