在储层极向预测中, 频谱分析是一重要的方法, 由于传统频谱分析方法的频率分辨率受信号长度的影响, 因而应用受到限制。本文采用的Marple谱方法, 对于短时窗的港分析具有较高的频率分辨率, 在储层横向预测中取得了很好的效果。

Frequency spectrum analysis is an important method in the lateral reservoir prediction. As the frequency resolution of conventional spectrum analysis method is influenced by the signal length, therefore its application is limitet. The Marple spectrum method used in the paper has a high frequency resolution for short-window spectrum analysis. A good result has been achieved in lateral reservoir predicion by us ing the method.
