Description

Technical Field

[0001] The present application belongs to the field of geophysical exploration technology, and specifically relates to a seismic data smoothing method and device based on slope information. Background Art

[0002] For the actual seismic data collected, there are often noise, abnormal signals and other influences, which lead to the decline of data quality and make it difficult to process and obtain better results. At this time, data smoothing technology is usually used to suppress or eliminate the influence of noise, abnormal signals and other factors to make the data more regular. However, excessive smoothing will destroy a lot of information in the original data and blur the details in the signal. At present, conventional smoothing methods have not considered the structural morphology, but directly use multi-point smoothing operators to perform filtering along three dimensions. Although it can achieve a good smoothing effect, it will destroy the original data information. Summary of the invention
