The application of logging data for the intelligent identification of sequence stratigraphic units

摘要

Sequence stratigraphy is an important theory in the field of earth sciences which can analyze the stratigraphy and sedimentary. But how to divide sequence stratigraphic units quantitatively is always a challenge and frontier in this domain. Based on the depth domain and frequency domain of logging data and former experts' study, and by the guidance of the classic sequence stratigraphy, this article has designed an intelligent identification method to divide sequence stratigraphic units. Based on the research of the accumulative parameter of sand clay ratio, the separate frequency scanning of depth domain, the full frequency scanning method and dominant frequency analyzing method, the software which can intelligently identify the sequence stratigraphic units is created. And this software has well applied in the analysis of real data.
