Detailed fracture system description

摘要

Detailed fracture system analysis lays the background for further precise structure and stratigraphy description. In this paper several fracture interpretation methods using seismic data are briefly discussed. Their mutual relation, evolution, advantages and weaknesses are also addressed. The approaches to computing three generations of coherence cubes, to extracting discontinuous enhancing attributes such as dip, azimuth, and chaos are summarized. A new graph thinning method adapted from computer vision processing is introduced, and a real data example is presented. It is pointed out that the quality of seismic data is the key to the successful application of these fracture delineation methods.
