In-depth Study Of The Seismic Data Processing Technology

Today, seismic data processing not only is conventional processing but also aims at serving geology and reservoir predicting.Geophysics,a kind of complex scienc, in whose field it is very difficult to get a new great achievement such as stack, on the way of development, has strong obstacle of some hard limits which limits it is application.Even there many modules in the seismic data processing system, more kinds of data exits in our work. In order to make modules work better, while need to study more deeply, some techniques which can not be applied dule to some limit need our efforts to transform the seismic data so that can be processed by these techniques.The subject aims the target of finding a way of soving practical problems by constructing some moduls, applying the technique more efficiently based on the achievements got already and technique exists.The strategy and result of seismic data processing are affected greatly by the data comes from field. Because of the seismic data acquired from not the ideal condition but unexpected field, what we can do to increase the signal-noise ratio is to attenuate noise in processing. Facing the problem that we always ask ourselves whether the technique and parmeters we use are suitable, we have to consider it in five main processing step, deconvolution, static correction, normal moveout, noise attenuation and migration. Signal can not be created but be enhanced by attenuating many kinds of noise from field by processing, so, is ridiculous to say , "Don't worry,we can get anything we want by processing" .The content of this paper consis of noise attenuation, amplitude compsation, deconvolution and retraced processing flows etc.This theme will illustrate some aimed processing in practice.
