Seismic Data Denoising Before Folding Method Research

Seismic data processing, is a very important project to noise, How can you change a contains all the types of complex interference seismic records profiles are processing, so it can have higher signal-to-noise ratio, and very high resolution, here said the resolution popular speak we can understand the effective wave signal or effective wave with phase axis can truly reflect the precision of the effective information underground interface, seismic data in the data processing technology is a very important and very challenging a subject, invalid signal, to this many predecessors and engaged in seismic data processing personnel is in constant efforts to seek a better method and idea to suppress the noise, the current denoising method and technology is also emerge in endlessly.In this paper according to different types of interference or noise put a different method, because of different interference with different characteristics and characteristics, Thus, this paper for all types of interference wave is summarized, and the mechanism of they produce, reasons and interference in the seismic records of earthquakes in the influence degree of the effective signal, the interference of the formation of the time and its strength, and any interference with classification, by its own characteristics to find out the characteristics of interference and characteristics, and so on, in this paper has a detailed introduction and analysis, and from his understanding puts forward some new understanding and knowledge summary. According to the different types of noise, combining with the different seismic data, the seismic data data can be decomposed to different domain or transform inside, for data features of these, the comparison of the characteristics of interference to find out the noise interference record position and try purify, different territory, the different space we can use different methods to find the most suitable for the interference of the noise removal methods. According to the characteristics of interference designed appropriate algorithm to noise suppression. In the study of the theory of method at the same time, I also have the aid of seismic data processing software and module, the study and master, at the same time for the train of thought of him summary on the ChengPing at the processing module development, research denoising technology. Finally, to pre-stack denoising method on the overall summary, and kinds of the denoising method in the advantages and disadvantages are discussed, denoising before stack of various methods in the application of the effect is analysed, accordingly, to fold the flow of ideas and denoising before a new understanding.
