Based on the core self-priming displacement experiment, the change of self-priming oil displacement and rock wettability of Gemini surfactant in different permeability cores is analyzed. The experimental results show that the self-priming oil displacement of core increases with the decrease of interfacial tension, and the larger the permeability of core is, the more the self-priming oil displacement is. At the same time, the wettability of core changes from lipophilic to hydrophilic. It is found that the relationship between the interfacial tension and the moisture index is logarithmic.
