在世界上许多地区,高频地震通常有严重的衰减、散射和频散,尤其不能提供探测基性盐(subsalt)岩等深层油藏勘探目标所需的有用信号。地震信号中的低频在反演处理中扮演了重要角色,通过这种方法,地震数据被转换为声阻抗剖面,并最终转换为油藏特性。地面地震数据常缺少精确反演所 In many parts of the world, high-frequency earthquakes typically have severe attenuation, scattering and dispersion, and in particular do not provide the signals needed to detect deep reservoir exploration targets such as subsalt rocks. The low frequencies in the seismic signal play an important role in the inversion process. In this way, the seismic data is transformed into acoustic impedance profiles and eventually converted to reservoir properties. Ground seismic data often lack accurate inversion
