摘    要:以测井资料为纽带,把小波分析与米兰柯维奇旋回结合起来,实现了地层持续时间的精确确定,进而计算了研究层段的沉积速率。利用滑动窗口和小波分析的方法找到了控制和影响盆地沉积演化的两种高频波动过程,高频波的识别为波动过程与层序地层学、与储盖组合的结合奠定了基础,提高了与波动分析有关的各项研究的精度,为其在生产实践中的应用开辟了道路.

关 键 词:年代地层框架    高频波    层序地层学    塔里木盆地

Abstract:Combining wavelet analysis with Milankovitch cycle by logging data, we accurately determine the continuous age of strata, and chronostratigraphic framework of Lower Silurian in Tarim Basin is found, then sedimentary rate of research section is calculated. Two high frequency wave processing are performed by sliding window and wavelet analysis, which control and influence the sedimentary evolution of basin, and the identification of which provides the possibility to combining wave processing with sequence stratigraphy and with reservoir and cap rock, and improves the accuracy of each research relative to wave analysis. On the basis of comparison and analysis of all data from wells, lithology and sequence, the figure of comprehensive analysis of high frequency wave is discoverd, which includes the information about curves of sedimentary rate, sedimentary circumstances, sequence and soon. Furthermore, we discovered the relations among high frequency waves, sequence and changes of sea level, between high frequency wave and reservoir as well as caprock.
Keywords:chronostratigraphic frame  high  frequency wave  sequence stratigraphy  Tarim basin
