Due to the complex surface condition and underground structure of mountain data,the abnormal development of interference wave is caused,which seriously affects the signal-to-noise ratio of seismic data.Based on the analysis of the quality of the original seismic data,a set of pre-stack and amplitude preserving combined denoising technology is formed by using targeted suppression technology for different noises.The application of actual data shows that the scheme can effectively remove noise interference,improve the signal-to-noise ratio of the target layer,and retain the weak signal and the low frequency effective signal of the data well,and the amplitude preservation is good,which lays a good foundation for the prediction of tight sandstone reservoir.
