在最近的年里,长偏移量的探索广泛地被使用了,特别在海洋的地震调查上。常规 AVO 分析为长偏移量的地震数据是不够的。为了拓宽应用程序, AVO 分析变化,我们在场对长偏移量的数据适用的新 P 波浪思考系数近似。我们的结果类似于能被当作近似到我们短偏移量的地震数据的结果的众所周知的 Shuey 公式。
In recent years, long-offset exploration has been widely used, especially on marine seismic surveys. Conventional AVO analysis is insufficient for long-offset seismic data. To widen the application range of AVO analysis, we present a new P-wave reflection coefficient approximation applicable to long-offset data. Our result is similar to the well known Shuey formula which can be treated as an approximation to our results for short-offset seismic data.
