Ｇａｒｄｎｅｒ与速度无关的ＤＭＯ方法首次成功用于中国东北某煤田地震勘探资料的处理。通过ＤＭＯ处理，地震时间剖面的信噪比、分辨率与连续性都获得改善。ＧａｒｄｎｅｒＤＭＯ方法是一种叠前偏移技术，它可以分为两步来实施：１）ＤＭＯ，这一步不需要使用速度，即与速度无关；２）ＮＭＯ，这一步的方程是通常的正常时差方程，即与倾角无关。它适用于陡倾角、构造复杂地区的勘探。 For the first time, Gardner’s velocity-independent DMO method is successfully applied to the seismic exploration data in a coalfield in northeastern China. Through the DMO processing, the signal-to-noise ratio, resolution and continuity of the seismic time profile are improved. GardnerDMO method is a prestack migration technology, which can be implemented in two steps: 1) DMO, this step does not require the use of speed, that is, has nothing to do with the speed; 2) NMO, this step of the equation is the normal normal transit equation , That is independent of inclination. It is suitable for exploration in steeply dipping, complex areas.
