Well logging sedimentology research is guided by the method theory of sedimentology and petrophysics, and solves sedimentology- related problems through different logging sequences. In order to better interpret the sedimentological information contained in well logging data, add vitality to well logging sedimentology research and eliminate its typical research misconceptions, this paper combining the literature of recent decades and the author's own work practice, elaborates on the origin, development and contemporary significance of well logging sedimentology. Firstly, the concept of well logging sedimentology, its development and research status are briefly reviewed. By combing the conventional logging sequences such as GR, SP and RT, which are more sensitive to markers of sedimentary facies, conventional well log facies elements, dip vector model and image log facies model and their corresponding relationship with sedimentary facies are analyzed, and the research contents and method flow of well logging sedimentology are summarized. On this basis, the application of geophysical well logging data in lithology discrimination, sedimentary structure discrimination and paleo- flow system recovery is analyzed. The facies markers reflecting different sedimentary microfacies can be extracted through the combination of conventional logs and image logs, and the process and matters needing attention for automatic logging discrimination of sedimentary microfacies are pointed out, and the fine description and evaluation process of vertical sedimentary microfacies superimposed sequences combined with logging and geology are summarized. Finally, the contemporary significance and development direction of well logging sedimentology research are pointed out in combination with historical missions of oil and gas exploration and development. The research results are expected to promote the further cross application between logging and sedimentary disciplines, and promote the theoretical progress of well logging sedimentology methods and the practical application of research results.
