共炮检距剖面模型的相位移算法

Phase shift method for estimating a common-offset section model

张叔伦，刘淑珍．共炮检距剖面模型的相位移算法．石油地球物理勘探，1997，32（6）：789～794本文运用平面波分析方法，提出了一种新的基于波动理论的共炮检距剖面相位移模型算法，并给出了公式的推导过程，得到了相应的广义上行波微分方程。共炮检距剖面的相位移算法是在波数域中建立的，它适用于常速介质的任意共炮检距剖面，还可以统一处理叠前和叠后的模型问题。理论模型试算证明了本文算法的正确性。

By using plane-wave analysis technique, we have developed, on the basis of wave theory, a novel phase shift method for estimating common-offset section mod-el. The paper describes the deduction of formulae and gives the relevant generalized differential equations of upgoing waves. The phase shift method for estimating common-offset section model works in wavenumber domain, and is suitable to any common-offset sections in constant velocity medium. What is more, it can cope with the problems relating to prestack and poststack modelings. Theoretical model-ing proves the method correct.
