摘要
分频解释技术已经越来越多的应用到地震储层预测和油藏描述中,成为地震解释的一种常规技术手段,分频解释技术中分频RGB颜色融合显示方法因其独有的视觉效果也开始受到关注.本文介绍了分频混色技术在高精度地震解释中的应用以及在应用过程中应注意的几点问题,包括优选高精度频谱分解方法、RGB颜色融合技术应用中频率选择的原则等.在此基础上,进一步探讨了分频数据RGB混色方法能有效解决地震沉积学中地层切片精度不满足薄储层预测的问题.RGB颜色融合显示方法能充分发掘高精度地震数据宽频的优势,得到精度更高的储层预测结果.
Spectral decomposition has been well used in seismic interpretation for reservoir description and prediction.And it has obtained much attention that plotting three spectral components against RGB color model components.In this paper,we discussed its application in high accuracy seismic interpretation and some skills including choosing the high accuracy spectral decomposition method and the principle to choose the high,middle and low frequency components to decompose.On the basis of that,we further discussed that the RGB plotting technique should be used for avoiding the problem that the same geologic body would not be plotted in one slice due to the horizon interpretation in high accuracy seismic interpretation with seismic sedimentology research.We can adequately extract the advantage high accuracy seismic data with wide bandwidth through RGB plotting technique to get high accuracy resevoir prediction result.
