摘要
针对当前层序定量划分方法存在的一些问题,提出一种基于多孔算法的平稳小波变换定量划分方法。利用理论模型验证该方法的有效性,并与常规的离散小波变换方法作对比,分析平稳小波变换的优越性。最后将该方法应用到南堡凹陷1号构造带W1井和W2井东营组一段的准层序组划分。研究结果表明:得到的层序划分结果与沉积背景和钻井结果相吻合,基于平稳小波变换的定量方法适用于层序地层划分工作,并为当前层序地层学研究向更高精度发展提供了定量化手段。
Based on a＇trous algorithm, the method of stationary wavelet transform was presented to solve the problems existing in the sequence quantitative division widely used today. Through the theoretical model, the effectiveness of the method was verified and the superiority of stationary wavelet transform over the conventional discrete wavelet transform was also analyzed. Finally, the method was applied into the division of para-sequence sets in two wells W1 and W2 in the first member of Dongying formation in No.1 tectonic belt of Nanpu sag. The results show that the division results is consistent with those of the sediment background and drilling, this method is suitable for the research of sequence quantitative division, and also provides an effective way for the development of sequence stratigraphy towards high resolution.
