【摘要】：为了提高当前工业化处理软件中单频干扰的处理效率,并降低常规处理流程的复杂度,提出并建立了一种高精度单频干扰并行压制新技术。该技术根据最小二乘最优逼近来逐道自动识别与自适应压制单频干扰,同时结合高性能并行处理算法,大大简化了常规处理流程。在XX工区实际地震资料中应用表明,该技术不受其他类型地震噪声影响,能够自动识别含单频干扰的地震道,且能精确得到单频干扰的频率、振幅和相位等信息,具有较高的振幅保真性和计算效率,处理效果优于工业化软件,为勘探成熟区地震资料保幅预处理提供了重要技术参考。
[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.
