谱分解是将一个短时窗内地震数据通过离散傅立叶变换或最大熵谱转换为频率域,利用频率一振幅谱来识别薄层和不连续地质体边界的新技术。由于断层对相位稳定性影响比较大,断层及其附近相位谱很不稳定,远离断层的位置相位谱相对稳定或呈渐变特征,故应用相位调谐体频率切片识别和解释断层,比传统的相位属性技术更加准确。对高 Spectral decomposition is a technique of transforming the seismic data in a short time window into frequency domain by using discrete Fourier transform or maximum entropy spectrum and using frequency-amplitude spectrum to identify the boundary between thin layers and discontinuous geological bodies. Because the fault has a great influence on the phase stability and the phase spectrum near the fault and its vicinity is unstable, the phase spectrum away from the fault is relatively stable or gradual. Therefore, the phase tuner frequency slice is used to identify and interpret the fault, Technology is more accurate. To high
