| 摘 要： | 利用沿井剖面滑动时窗内的ＦＦＴ和最大熵谱估计算法，选择合适的滤波器、窗长和步长，从测井曲线中分析出了Ｍｉｌａｎｋｏｖｉｔｃｈ周期．研究了波长比，谱峰等特征与周期的关系，确定出沉积速率的渐变与突变，求出了沉积速率，经分析，与岩性结果相符合．

| Abstract: | Milankovitch cycles were discovered by FFT and Maximum Entropy spectraestimation within a sliding window along logging profile using right fliters, window length and steps. Wave length ratio and character of wave peaks and their relations were studied. Continuous and sharp changes were found and proved by lithologic analysis. |
