The invention relates to a method for performing weight analysis on main control factors of logging parameters in a water-oil-gas reservoir. The method is characterized by comprising the following steps: 1, collecting and sorting various characteristic parameters measured by each single technology in geochemical logging, collecting oil testing conclusions corresponding to each group of characteristic parameters, and then cleaning and verifying integrated data; 2, performing standardized processing; 3, writing a ReliefF characteristic selecting program by using Matlab software, and establishinga ReliefF algorithm model for geochemical logging measurement analysis; 4, inputting standardized data into the ReliefF algorithm model, and calculating weight values of the various characteristic parameters measured by the single technology by using the RelefF algorithm model; 5, setting thresholds, screening characteristic subsets, and extracting geochemical logging sensitive parameters. The method and a gray correlation analysis method have different emphases; by the method, the defects of the gray correlation analysis method in the weight analysis are overcome; the method belongs to supervised learning.
