Abstract：Logging trace is a basis of geologic strata-par-tition,but the multi-solution and limitation exist when only using a single logging trace to solve the complex geologic issues.In order to overcome the multi-solution,the people use multiple logging traces for geologic strata-partition and the preci-sion of strata-partition is improved.On that basis,the paper suggests a method,in which the separate weighting factors are assigned to multiple logging traces and then normalization processing is carried out,forming one nominal integrative parametric logging trace.The integrative parametric trace gives emphasis to common information of selected multi-logging traces and reduces or weakens occa-sional errors in a single logging trace,which in-creases the believable degree of post-integrative logging trace.The method can be used for strata-partition,lithologic analysis and oil/gas-bearing prediction etc.Note that there is no such case at all that the more selected kinds of logging traces the better when using the method,it must select the logging traces that can reflect the characters of for-mation units instead.
