| 摘 要： | 除了泊松比外,有不少非目标因素会引起振幅随炮检距变化,在AVO属性叠加图上能直观看到它们的影响。AVO的抗干扰性能远低于水平叠加,那些振幅或时差随炮检距单调变化的因素会引起严重的假AVO异常,因此利用AVO方法时,需要作特别精细的叠前处理。

| Abstract: | Besides Poisson's ratio there are quite a few aimless factors which can cause AVO. One can see their effect directly from diagraphs of AVO attribution superimposition. Anti-inter- rupted ability of AVO is far smaller than horizontal stack. Factors which are of monotonous variation of amplitude and time shift with off-set can form serious spurious anomalies. It is even bigger than those caused dy poisson's ratio so AVO needs peculiar meticulous processing before stack. |
