Description

TECHNICAL FIELD

[0002] For actual collected seismic data, noise, abnormal signals and the like often exist, which leads to a decline in data quality and makes it difficult to obtain good results through processing.

However, excessive smoothing can destroy much information in the original data and blur details in the signals. The conventional smoothing method does not consider the structural morphology, but directly uses a multi-point smoothing operator to perform filtering processing along three dimensions. Although a good smoothing effect can be achieved, the original data information is destroyed. SUMMARY
