Positive and negative interval divisions of dynamic pressure signal was proposed. The differences of weighted signal sums,signal mean values,signal peaks of every two successive intervals were selected as the features of leak signal,and their calculations and relative scaling transformations were presented. The feasibility criteria for lengthwise and breadthwise evaluation of leak signal features were presented,and evaluation was done with features extracted from field data and the feasibility was verified.
