位于澳大利亚北西大陆架地区的Browse盆地中的礁体,在其侧腹很有代表性地具有强烈的横向速度不均匀性,并形成了一个不规则的海底地貌。当在共中心点(CMP)道集上的时差不再是双曲线时,这两种因素淡化了常规速度分析的效果。随后,在礁体侧腹的速度结构能恰当地被分辨。如果在邻近地区采集到 The reefs in the Browse Basin, located in the North Western Shelf region of Australia, are characterized by intense lateral velocity inhomogeneities on their flanks and an irregular submarine topography. When the time difference on a co-ordinate (CMP) gathers is no longer a hyperbola, both of these factors downplay the effects of conventional velocity analysis. Subsequently, the velocity structure at the flank of the reef can be properly resolved. If collected in the vicinity
