本文介绍一种能够获得油松比剖面的AVO反演方法。这种方法简便易行, 运算速度快, 对发现及追踪与含天然气层有关的低泊松比异常效果明显。采用这种方法有助于减少AVO常规处理资料解释中产生的“陷阱”, 进一步提高AVO方法的应用效果。

The papcr prcsents a mcthod to producc Poisson's Ratio sections via AVO invcrsion. The method is easy to operate, efficient in computation, and yields good tesults in finding and tracing weak Poisson's Ratio anomalies associated with gas-bearing layers.The method is advantageous to the reduction of "pitfalls" in conventional AVO interpretation and thus provides an improvement for the AVO technique in application.
