| 英文摘要 | The paper develops the method of mono-scale fractional-order Gaussian wavelet transform singularity algorithm, based on the conventional algorithm for singularity positions and strength index. The improved method realizes the detection of singularity polarity. The geologic significances of logging data singularity information are also presented, according to our analysis, the singularity positions indicate the sequence stratigraphic boundary, and there is a subtle relationship between the singularity strength index and sedimentary environment, meanwhile the singularity polarity can be used to recognize stratigraphic base-level cycle. Based on all those above, we propose a new method of sedimentary cycle analysis method based on the singularity information of logging data with multiple scales. The method overcomes the disadvantages in conventional method, and provides a quantitative tool for judging interface of stratum sequence. Good results were achieved in the actual application. |
