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 seclion is calculated. Two high-frequency wave processing are performed by sliding window and wavelet analysis which control and influence the scdimcntarv evolution of hasin, and the identification of which provides the possihilitv 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.
