地震数据结构张量相干计算方法
|
摘要
在研究前三代地震相干算法的基础上,提出了一种基于地震数据结构张量的相干属性计算方法和流程。该方法将地震数据瞬时相位作为数据输入,利用复地震道数据信息对地震数据结构张量的偏导数求取进行平滑处理,较好地解决了由于地震资料中噪声的存在而产生的计算不稳定性,且利用纵、横向的瞬时波数计算可以得到地震数据的视倾角和方位角属性体。实际三维地震数据的计算结果验证了地震数据结构张量相干计算方法的有效性,计算出的相干属性体分辨率更高,断层的展布形态更清晰。
We presented a computation method and workflow of seismic data coherence attribute based on structure tensor.This scheme uses seismic data-driven method to calculate directly coherence property data,which can improve the quality of calculation results.The proposed coherence calculation method is based on the structure tensor principle;the input data is the instantaneous phase information of seismic data and improves the third coherence method.This method not only keeps the signal-to-noise ratio,but also improves the resolution of computed coherence property volume.In this paper,we computed coherence coefficients cube respectively using the normal method and the proposed scheme with a reality 3D seismic data,the calculated results indicate the proposed scheme is correct and effective.Moreover,the calculated coherent attribute cube has higher resolution and the distribution of faults is clearer.
