The method is fast and thus appropriate for real - time applications since no iterative operation is involved 提出的算法在尋找最優(yōu)閾值的過程中無需迭代計算,因此速度快,適合于實時應用。
In view of characteristics of seismic data of gobi - sand dune areas , this paper , through various data - processing means such as quality control , high - pass filltering , dip angle filltering , field static correction , surface consistency deconvolution , precise velocity analysis , denoising before stack , multiple iterative operation of residual static correction , denoising after stack and modification after shift , has raised the data quality of seismic profiles in low signal - to - noise ratio areas and managed to form the seismic data - processing technique for such complex areas as gobi , foreland and dune 摘要針對戈壁、沙丘地區(qū)地震資料的特點,通過對原始資料進行質量控制、高通濾波、傾角濾波、野外靜校正、地表一致性反褶積、精細速度分析、疊前去噪、剩馀靜校正多次迭代、疊后去噪和偏后修飾等處理,提高了低信噪比地區(qū)地震剖面的資料質量,摸索出了一套戈壁、山前、沙丘等復雜地區(qū)地震資料處理技術。
