| 英文摘要 | Surface-related multiples penetrate into the subsurface several times and contain abundant reflection information of small angles. Compared with primaries, they sometimes can provide higher fold and better illumination for subsurface. Instead of trashing multiples as noises during the seismic data processing, nowadays, a lot of methods have been proposed to image multiples. Conventional migration methods have been modified for directly imaging multiples, e.g., Kirchhoff migration of multiples, wave equation migration of multiples, or reverse-time migration (RTM) of multiples. Alternatively, the linear two-step procedures can be utilized for imaging multiples. Primaries can be extracted from multiples based on seismic interferometry or focal transformation, and then imaged by utilizing conventional migration methods. However, most methods for imaging multiples would generate so many artifacts due to the undesired interactions between seismic-events (i. e. primaries and different-order multiples), which are hard to be attenuated and seriously pollute the true-image. Moreover, the least-squares based focal transformation can transform first-order multiples into primaries, second-order multiples into first-order multiples, etc., with few noises generated. Multiples focal-transformed from higher-order multiples can be eliminated by surface-related multiples elimination (SRME). And then, primaries focal-transformed from first-order multiples can be imaged by any conventional migration methods, and we call the procedures focal transformation imaging of first-order multiples. |
