In ordinary reflection seismogram, the refraction wave was strongly interfered. But by using i-p transformation,the refraction recorded could be enhanced and thuswise the static correction could be performed with the data provided by the refraction. Based on what is mentioned above,a technique of making static correction with enhanced refraction by τ-p transformation was put forward. With this technique recommended, the hard nut of making static correction in converted wave exploration could easily be cracked....

本文提出利用τ-p变换,使反射波记录上被强烈干扰的折射波得到突出和加强,从而求准静校正量的方法。使用这种方法可以方便地解决转换波勘探中复杂的静校正问题。

Both P wave and SV wave can be received by vertical geophone,or horizontal geophone in the converted-wave survey in which P-wave source,vertical geophone and horizontal geophone along seismic line are used simuhaneously.How P wave or SV wave can be recognized and separated out is an important matter in converted wave data processing.Vector composition method can be well used to achieve this when the assumption of horizontally-layered medium is made.The key to the suc- cessful use of this method in accurate...

在用 P 波震源、一个垂直检波器与一个沿测线方向的水平检波器的转换波勘探中,垂直检波器和水平检波器都会接收到 P 波和 SV 波。所以,如何辨认和分离 P、SV 波就成为转换波资料处理中的一个重要步骤。在水平层状介质的假设条件下,利用矢量合成方法能较好地实现运个目的。由于该法对速度比较敏感,故取准速度(其中包括地表低降速带的速度)是该方法成功的关键。

Four problems about the application of converted A-SV-Waves seismic explorationare discussed in this paper on the basis of the results of P-SV-Waves survey tests in Jiang su and Sichuan provinces. First,the conception of dominant converted wave is presented according to a large amount of AVO curve analysis and its pattern and optimum gatheringrange are determined.Second, the distinquishing of converted wave is discussed in seismicrecords and profiles. Third, one-step method of common conversion point (cop) atack...

First,the conception of dominant converted wave is presented according to a large amount of AVO curve analysis and its pattern and optimum gatheringrange are determined.Second, the distinquishing of converted wave is discussed in seismicrecords and profiles. Third, one-step method of common conversion point (cop) atack is introduced, which can complete reflection point migration, non-hyperbolic moveout and copstack procedures at the same time. Finally, the geological significance of converted .waveseismic section is discussed.

根据江苏和四川油区转换波勘探试验的结果,作者讨论了转换波应用中的四个问题,首先由大量的AVO曲线的分析,提出了主转换波的概念,确定了主转换波的波型;确定了接收主转换波的最佳采集范围。其次讨论了在实际地震图中如何识别转换波。然后,文中介绍了转换波共转换点(CCP)叠加的一步法[1],将反射点精确归位、非双曲线动校和CCP叠加一步完成。最后讨论了转换波剖面的地质意义。
