与其他海上资料一样,多次波也是浅剖资料中存在的突出问题.多次波的去除对提高浅地层剖面的质量具有重要的意义.SRME技术是一种衰减自由表面多次波较为有效的方法,目前已在海上多道地震资料多次波压制中得到广泛应用,但在单道或浅剖资料中的应用还比较少,将该方法应用于浅剖资料处理中能否取得好的多次波压制效果是一个值得去验证的问题.本文阐述了SRME技术的基本原理,并采用模型数据对其主控参数进行了试验,最后将SRME技术应用于实际浅剖资料的多次波衰减处理中,它有效地消除了资料中的多次波,验证了该方法对浅剖资料多次波压制的有效性和实用性,通过与浅剖资料处理中常用的预测反褶积方法去除多次波的效果相比,SRME更具优势.
As with other maritime data, multiple waves are also prominent issues in shallow profile data.Multiple wave removal is of great significance to improve the quality of shallow stratum profile.SRME technique is a more effective method to attenuate free surface multiples Method has been widely used in multi-wave suppression of multi-channel seismic data at sea, but its application in single-channel or shallow-profile data is still relatively small. Whether this method can be applied to shallow-profile data processing can be achieved well The sub-wave suppression effect is a problem that deserves to be verified.This paper describes the basic principle of SRME technology, and uses the model data to test its main control parameters. Finally, the SRME technique is applied to the multiple attenuation of real shallow profile data , It effectively eliminates the multiple waves in the data and validates the effectiveness and practicability of the method for suppressing multiple-wave data in shallow profile data. The method can be used to remove multiple times by common prediction deconvolution methods used in shallow profile data processing Compared with the effect of waves, SRME has more advantages.
