谱分解技术在W区河道识别中的应用

Application of spectral decomposition method in channel identifying at W area

随着油田勘探开发形势的发展,薄储层预测及特殊地质体的识别在岩性油气藏中越来越重要,频谱分解技术在其中的作用越来越明显.本次在w区在常规方法无法对储层进行有效识别的情况下,通过WVD时频分解技术,在该区准确的找到了河道沉积体.

With the development of the exploration and exploitation in oil field, the prediction of thin reservoir and identification the special geology body plays a more and more important role in lithologic traps, so does the spectral decomposition. In this area, normal method can not identify the reservoir effectively,but in this paper, with the WVD time-frequency spectral decomposition method, we can sculpt the channel deposit body well.
