The present invention relates to the well drilling field in petrochemical industry, in particular to use of dual-cation fluorocarbon surfactant as amphiphobic wettability reversal agent in drilling fluid. The dual-cation fluorocarbon surfactant is a dual-cation fluorocarbon surfactant of which the cation part is represented by the following formula (1). The dual-cation fluorocarbon surfactant of the present invention can serve as wettability reversal agent when it is used for oil-gas drilling to enable rock amphiphobic, and is an amphiphobic wettability reversal agent which can cause rock surface to be non-hydrophilic and non-lipophilic. Using of dual-cation fluorocarbon surfactant, especially when drilling highly hydrous mud shale, can avoid permeation of water and oil into the rock effectively and thereby a capillary phenomenon can be prevented, and an effect of stabilizing the well wall and protecting the reservoir is attained.
