多次波是地震勘探中一种常见的干扰波，巴楚地区浅层强反射界面导致了多次波异常发育，严重影响了地震数据的成像，甚至产生了构造假象，压制多次波对于新疆巴楚地区地震数据的构造精确成像具有重要的理论意义与实用价值。结合巴楚地区地质结构特征，对地震采集的原始数据进行深入剖析，同时根据多次波自身的特点，在试验了多种技术方法之后，认为拉东变换压制多次波方法能够在该区取得地震数据构造成像满意的效果。给出了在不同数据域准确识别多次波的几种基本方法和判断准则，同时详细阐述了拉东变换压制多次波的基本原理。通过工区实际资料的处理，系统地演示了该技术方法运用的过程、结果及关键点。

Multiples is one of the most common interference wave in seismic exploration.In Bachu area,the shallow promi-nent reflecting interface creates the abnormal development of multiples which definitely effects the quality of seismic image.E-ventually,it will result the fake structure.Considering the geological structure in the local area,after raw data analysis and dif-ferent test based on the features of multiples,the application of Radon Transform has an excellent performance on multiple at-tenuation in this area.In this article,several methods of multiple recongnition in the different data domain will be illustrated as well as the principle of multiples attenuation with Radon Transform.Through the processing of real seismic data in this area, some research of Radon Transform will also be discussed with personal opinion.
