Seismic imaging systems and methods employing correlation-based stacking |
摘要 |
Disclosed systems and methods provide enhanced seismic images through the use of partial image stacking weights that are based on the resemblance between the local partial image and a reference image. At least some method embodiments include obtaining partial images of a survey region and stacking the partial images to produce a reference image. The partial images are then recombined to form an enhanced image, wherein the recombining includes: measuring at each point the reference image's similitude with each of the partial images; and determining at each point an enhanced image value from a weighted combination of corresponding values in the partial images, the weighted combination using weights derived from the reference images' similitude at that point to each partial image. |
