摘要： Systems, media, and methods for processing seismic data are disclosed. For example, in one embodiment, the method may include receiving a plurality of partial image partitions of a migrated seismic image, and stacking the plurality of partial image partitions such that a first image is generated. The method may also include aligning the plurality of partial image partitions based at least partially on the first image. Aligning may include adjusting at least one of the plurality of partial image partitions and generating a displacement field. The method may also include, based at least in part on the displacement field, stacking the plurality of aligned partial image partitions to generate a second image. The method may further include based at least in part on the second image, realigning the plurality of aligned partial image partitions.

摘要： A method for generating an image of a subterranean formation includes receiving seismic data that was collected from seismic waves that propagated in the subterranean formation. Partition images are generated using the seismic data. A geological model of the subterranean formation is generated. Dip fields in the partition images are determined. A target dip field in the geological model is determined. A degree of correlation between the respective dip fields and the target dip field is determined. Weights are assigned to the partition images based upon the degrees of correlation to produce weighted partition images. The image of the subterranean formation is generated by stacking the weighted partition images.
