摘要
在实际野外地震资料处理工作中,合理地选取压制方法,是获得高品质地震剖面的关键,虽然目前压制多次波的方法有很多,但是不存在最优的多次波压制技术可以适用于所有情况。本文首先从几种常用多次波压制方法的原理和适用范围出发,利用各种方法的压制特点组合压制共反射点道集浅层、远偏移距和近偏移距三个区域不同类型多次波,并将这一套组合压制方法应用于多次波严重的地区,最后取得令人满意效果。
In the actual field seismic data processing work, selecting attenuation method reasonably is the key to get high quality seismic section, there are many multiple attenuation methods at present, but there is no optimal multiples attenuation technique can be applied to all situations. In this article, firstly, the author explaine the principle and the using range of common multiples attenuation method,then use characteristics of various methods to suppress multiples, which locate in the shallow, far offset and near offset area of common reflection point gathers, and let the combination attenuation method apply to the region which have much multiples,we obtain satisfactory result lastly.
