运用频谱分析方法在塔里木盆地塔中地区志留系识别出米兰柯维奇旋回 .对米氏旋回进行波动分析表明 ,高频率的 5Ma周期波波动特征能够有效地解释生、储、盖演化 .周期波表现为峰峰叠加 ,为储层发育期 ;周期波表现为谷谷叠加时 ,为盖层发育期 .高频波由波峰→波谷过渡的特征 ,刚好对应层序地层学的海进体系域→高位体系域的变化 .
The Milankovitch cycle is identified by the spectral analysis method in the Silurian of Tazhong area, Tarim Basin. The fluctuation analysis of the Mie cycle shows that the 5Ma periodic wave with high frequency can effectively explain the evolution of the source, reservoir and cap. Is the peak and peak superimposition, which is the reservoir developmental period.The periodic wave shows the period of caprock development when the valley is superimposed.The characteristic of the transition from crest to trough is just corresponding to the sequence stratigraphic transgressive system tract → highstand system tract The change .
