Seismic Fracture Detection Based on Multi-scale Complete Lattice Morphological Seismic Image Enhancement Method

In order to improve fracture prediction method of noise suppression capabilities and edge detection accuracy, the paper introduces mathematical morphological operator, proposed a Multi-scale morphology of the fracture detection method. The method firstly get three-dimensional post-stack seismic data time slices, the second type of preferred structure for the noise elements of the template, and then suppresses the noise by morphological filtering, and detecting edge by morphological edge detection, finally fracture prediction using edge information. Actual data results show that the proposed multi-scale morphology based on the fracture-detection method better suppression of noise, and to ensure the accuracy of edge detection, their test results with the conventional The stress field analysis and drilling data consistent with the results.
