Abstract: Based on the theory of Darcy 's law and solute transport, this paper took a groundwater-sealed oil depot project on a certain island as the engineering support and, conducted numerical simulation research using COMSOL finite element software to analyze the variations in seepage field in caverns under different design schemes. The water seal safety in caverns was evaluated, and the development degree of seawater intrusion was investigated. The research indicated that the project required the installation of a horizontal water curtain, and the design pressure value of the horizontal water curtain should not be less than 0.2 MPa. The variation in the depth of the main cavern had a small impact on the water seal. When the reservoir area was fully excavated without oil storage, seawater would intrude into the caverns, with seawater intrusion showing a pattern of rapid intrusion followed by gradual intrusion, entering from the bottom of the main cavern.
