说明：  AVO（Amplitude Versus Offset,振幅随偏移距的变化）技术用于研究地震反射振幅随炮点与接收器之间的距离即炮检距（或入射角）的变化特征来探讨反射系数响应随炮检距（或入射角）的变化, 进而确定反射界面上覆、下伏介质的岩性特征及物性参数。借助AVO 分析，地球物理学家可以更好地评估油气藏岩石属性，包括孔隙度、密度、岩性与流体含量。
(AVO (Amplitude Versus Offset, amplitude variation with offset) technologies used to study the seismic reflection amplitude with distance shot and receiver variation between that gun seized from (or incidence angle) to investigate the response of the reflection coefficient with gun offsets (or incidence angle) changes, and to determine the reflector cover, lithology and physical parameters of the underlying media. With AVO analysis, geophysicists can better assess reservoir rock properties, including porosity, density, lithology and fluid content.)
