Embodiment Construction
[0049] The present invention is to provide a method for detecting fracture-vug development zones based on iterative three-parameter wavelet transform, which processes two-dimensional seismic slices for identification of fracture-vug development zones and effectively guides reservoir prediction for oil and gas geophysical exploration .
[0050] The present invention can achieve following purpose:
[0051] (1) Using three-parameter wavelet transform instead of conventional wavelet transform for calculation, to overcome the defect of poor matching of seismic data in the prior art;
[0052] (2) Carry out edge detection processing to the horizontal and vertical of 2-dimensional seismic slice simultaneously, adopt the root mean square of the result of horizontal and vertical edge detection as final edge detection result, improve the precision of the edge detection of prior art;
[0053] (3) Further improve the precision of the edge detection of prior art, adopt iterative process, p...
