摘要
对于反射波海洋地震勘探而言,多次波是主要干扰波之一,必须进行去除,否则会严重影响地震勘探的质量。多次波有很多不同类型,产生机制各不相同。目前去除多次波的方法很多,方法原理不同,每种方法只对某一类型的多次波有较好的处理效果。任何一种单一的方法都很难达到理想的处理效果。本文先分析了SRME技术、t-x域预测反褶积、高精度radon变换技术的基本原理,然后结合这三种方法的优点,采用组合方法对南海某工区的地震勘探资料进行了处理,经过对比分析,道集和叠加剖面上多次波都得到很好地压制,提高了叠加剖面质量,处理效果良好。
Multiple waves are the most common noise in marine seismic data, which can af fect the quality of geo--detection. There are many kinds of multiples, and many ways can be used to process multiple waves, but each method can only depress one of them. A per- fect result cannot be obtained by only one of these methods. In this paper, the principle and application of three multiple attenuation methods： SRME, t--x prediction deconvolution, and high resolution radon transformation are discussed. At last, combination methods are used to attenuate multiples in marine seismic data, and a good result is achieved.
