摘要
文章利用子波沉积相预测方法,在井旁的地震记录中提取出研究目的层的优势相所对应的地震子波,经研究发现,沉积相的改变和地震子波的变化存在一定的关联。利用从井中提取到该优势相的地震子波对研究目的层进行相关计算,就能够预测这种优势相。分别提取在不同沉积微相控制下生成且彼此重叠的砂体,有助于实现对单一砂体的识别,这对砂体十分发育的川东南河流相沉积区会有重要的研究价值和实用价值。
The wavelet-related sedimentary facies method is used to extract superior facies of target layer corresponding to wavelet from seismic recorder beside the well.Research shows that there is certain correlation change of the sedimentary facies change of seismic wavelet.Correlation calculation of target layer by superior phase seismic wavelet extracted from well can predict the superior phase.Extraction of sand bodies which are overlapped and formed under micro-sedimentary facies is helpful to recognize single sand body thus is valuable for study and practice use in the southeast Sichuan province where sand bodies are well developed in river sedimentary areas.
