%X Focusing on the well-logging curve with an axis of depth to reflect geological information and similarity analysis of time series, this paper proposed a searching method of well-logging curve similarity based on the morpholo-gical characteristics. Using the method of comprehensive activity analysis to divide the well-logging curve into contrast subsequences, and combined with the morphological characteristics, including sequence trend, depth span, and fluctuation range. This paper aimed at measuring the similarity of contrast sequences by weighting the slop difference. This method put an emphasis on the morphological changes, described the morphological differences effectively, and had definite physical meaning. The experiments show the effectiveness of this method.
