Based on the electrical imaging logging, the watershed algorithm is applied to the identification of the gravel in the electrical imaging logging figure, and the parameter selection of the watershed algorithm directly affects the recognition result. Different optimal parameters are selected for each step of watershed algorithm to identify the gravel and the processing results are compared and analyzed. Finally the optimal parameters of watershed algorithm to identify the gravel are determined. The result is good when the optimal parameters is used to AA wells, BB and CC wells of Jilin Wangfu Fault Depression.
