    • Abstract
  • For meeting the demand of building fine geologic correlation framework,the wavelet analysis technique was chosen to study the stratigraphic division and comparison,according to the plentiful data and the feature of mode extreme point of wavelet factor and zero crossing point and signal discontinuity model.By means of the wavelet changing on conventional logging curves,through selecting detail signals of third layer,log was reconstructed.Then the fine correlation section was built by combining the new log curves and the conventional log curves.Moreover,the technique was introduced for analysis of barrier and interbed.The study indicated that the result of stratigraphic division and comparison and analysis on barrier and interbed is reliable,the research meets well the demand of high definition sequence division,the effect is better than the traditional method.
