Abstract：By combined with the practice of oil field logging stratigraphic, the principal and method of special logging-stratigraphy are described. Some logging stratigraphic connotations are generalized, including the characteristics of combinations, the characteristics of relative stability and easy change, and complete stratigraphic sequence, etc. The four key steps of stratigraphic division and correlation are also summarized as follows:(1) distinguishing the logging characteristics of relative stability and easy-changed formations; (2) establishing a complete stratigraphic sequence; (3) developing the standard section in areas; (4) dividing formations in areas and contrasting the formations. The logging stratigraphic correlation is refined by using the method; and it is not only promoting the prosperity of the stratigraphy research, but also beneficial to the production and research work of oilfield.
