摘要
随着油气勘探难度的不断增大,勘探目标变得越来越复杂,对地震数据处理的质量也有了更高的要求.一般来说,只有信噪比达到一定的水平,地震资料处理才可能实现良好的保真度.当今的地震勘探正向着深层、复杂构造和岩性勘探的方向发展迈进.本文介绍了目前业界比较有特色的去面波技术,其中包括自适应相减和Curvelet变换的组合压制面波技术、基于时频域极化属性的多分量地震资料面波衰减、f-k域的交叉扩散三维倾角滤波,基于深度学习的地震散射面波技术方法加以介绍,对智能化去面波技术的前景做进一步的展望.
With the increasing difficulty of oil and gas exploration,the exploration target becomes more and more complex,and the quality of seismic data processing is required to be higher.Generally,seismic data processing can achieve good fidelity only when the signal-to-noise ratio reaches a certain level.Nowadays,seismic exploration is moving towards the direction of deep and complex structures and lithology exploration.This paper introduces some the characteristic surface wave removal techniques in the industry,including the combined suppression surface wave technique of adaptive subtraction and Curvelet transform,surface wave attenuation of multi-component seismic data based on time-frequency domain polarization property,cross-spread 3 D dip filtering in f-k domain and seismic scattering surface wave technology based on deep learning is introduced.The paper also makes a further prospect of the intelligent technology of surface wave removal.
