The Application Research Of Seismic Data Consistent Processing

The working area involved study has a particularly complex surface conditions and geological environments.The surface elevation is rough acutely.There is sedimentary gravel in the valley and its thickness changes acutely in horizontal direction which causes the seismic data has low ratio of signal to noise,and some regions have obvious statics.The energy,and frequency of seismic shot is difference between shots from difference portion of working area,it is necessary that eliminating the differences of seismic Wavelet to ensure the good consistency of seismic data processing.The main processing measure carrying out during consistency processing of seismic data including amplitude processing,matching filter,deconvolution,statics correction,these can improve the consistency of the wavelet.According to the analysis of the original data,The research get the conclusion that ratio of signal to noise,statics correction and resolution is the most three important work in improving the consistency of seismic data processing.On the basis of above conclusion,The research has completed many parameters tests of seismic processing,and got the get suitable processing flow and parameters of seismic data.
