摘要/Abstract

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 diaRraphs of AVO attribution superimposition. Anti-interrupted ability of AVO is far smaller than hortzontal stack. Factors which are of monotonous variation of amplitude and time shift with off-set can form seripus spurious anomalies. It is even bigger than those caused dy poisson's ratio so AVO needs peculiar meticulous processirta before stack.
