可靠的井间反射波成象是一项复杂的工作,即使在时间域中完成波场分离后,数据中仍然存在剩余的强相干噪声。由于用于成象的反射角范围较宽,叠加变得较为复杂。对有几英尺长的波长而言,速度或几何误差使得波至不能校直,存在很小的误差,从而产生相消干涉,降低了叠加图象的质量。本文介绍了一种能解决该复杂问题的成象方法,它使我们能从大量 Reliable crosswell reflection imaging is a complex task, and the remaining strong coherent noise remains in the data even after the wavefield is separated in the time domain. Overlapping becomes more complicated due to the wide range of reflection angles for imaging. For a few feet of wavelength, the velocity or geometric error makes the wave impossible to align, with small errors, resulting in destructive interference and degrading the quality of the overlay image. This article describes an imaging method that can solve this complex problem, which allows us to work in large numbers
