高精度拉东变换技术在多次波压制中的应用

Application of High Precision Radon Transform in Multiple Suppression

多次波的存在会降低地震资料的品质,对后续的油气勘探开发造成严重影响。一直以来,多次波压制都是地震资料处理人员关注的热点和难点。主要对高精度拉东变换技术在多次波压制中应用进行了分析与探索,首先阐述了多次的形成机理、多次波的类型以及多次波的特点,然后分析了常规拉东变换和高精度拉东变换压制多次波的基本原理,最后结合实际地震资料,对比分析了两种拉东变换压制多次波的效果。应用效果表明,高精度拉东变换可以取得更好的压制效果。

The existence of multiple waves will reduce the quality of seismic data and have a serious impact on subsequent oil and gas exploration and development.For a long time,multiple suppression has been the focus and difficulty of seismic data processing personnel.This paper mainly analyzes and explores the application of high-precision Radon transform in multiple suppression.Firstly,the formation mechanism of multiple,the types of multiple and the characteristics of multiple are described respectively.Then,the basic principles of conventional Radon transform and high-precision Radon transform to suppress multiple are analyzed.Then,combined with the actual seismic data,two kinds of Radon transform suppression are compared and analyzed The application results show that the high precision Radon transform can achieve better suppression effect.
