在地震反射成像中,术语“偏移”通常被描述成一种策略。利用这种策略,可以把时间域原始反射(如共炮点剖面或共偏移距剖面)变换到地下反射面的正确空间位置。“偏移”还可被描述成另一种策略,即在时间域直接把原始反射变换到时间偏移的位置。最近,“偏移”这个词已经被用来描述一种处理,这就是把在共偏移距(CO)剖面上观测到的原始反射变换到它们在零 In seismic reflection imaging, the term “offset” is often described as a strategy. Using this strategy, it is possible to transform the original reflection in the time domain (such as a common shot-point profile or co-offset profile) into the correct spatial position of the subsurface reflector. “Offset” can also be described as another strategy, which transforms the original reflection directly to the position of the time offset in the time domain. Recently, the term “offset” has been used to describe a process that transforms the original reflections observed on a co-offset (CO) profile to their zero
