【摘要】:為了提高當(dāng)前工業(yè)化處理軟件中單頻干擾的處理效率,并降低常規(guī)處理流程的復(fù)雜度,提出并建立了一種高精度單頻干擾并行壓制新技術(shù)。該技術(shù)根據(jù)最小二乘最優(yōu)逼近來逐道自動(dòng)識(shí)別與自適應(yīng)壓制單頻干擾,同時(shí)結(jié)合高性能并行處理算法,大大簡化了常規(guī)處理流程。在XX工區(qū)實(shí)際地震資料中應(yīng)用表明,該技術(shù)不受其他類型地震噪聲影響,能夠自動(dòng)識(shí)別含單頻干擾的地震道,且能精確得到單頻干擾的頻率、振幅和相位等信息,具有較高的振幅保真性和計(jì)算效率,處理效果優(yōu)于工業(yè)化軟件,為勘探成熟區(qū)地震資料保幅預(yù)處理提供了重要技術(shù)參考。
[Abstract]:In order to improve the processing efficiency of single frequency interference in current industrial processing software and reduce the complexity of conventional processing flow, a new technique of parallel suppression of high precision single frequency interference is proposed and established. Based on the least square optimal approximation, this technique automatically recognizes and adaptively suppresses single-frequency interference, and combines with high performance parallel processing algorithm, simplifies the routine processing flow greatly. The application in the practical seismic data of XX area shows that the technique is not affected by other types of seismic noise, it can automatically identify seismic traces with single frequency interference, and it can accurately obtain the frequency, amplitude and phase information of single frequency interference. It has high amplitude fidelity and calculation efficiency, and the processing effect is better than that of industrial software, which provides an important technical reference for the amplitude preserving preprocessing of seismic data in mature exploration area.
