  • This paper bases on hydrogeological reconnaissance and hydrological experiments of work areas, constructs a 3D numerical model using FEFLOW software, calculates the related results, carries out spatial investigation using ARCGIS software, and enables experts to obtain numerical values of various parameters in the construction and operation of underground water-sealing oil storage in rock caverns, like water level change, water inflow, and size and scope of drawdown funnels, providing a basis to the construction of underground water-sealing oil storage in rock caverns and ensuring their operation and construction safety and economy. It takes the underground water-sealing oil storage in rock caverns in Yantai as an example, and accomplishes simulation prediction of water inflow and supply water volume of relevant water curtains during the oil storage caverns construction/operation periods. In the construction period, the oil storage caverns have stable water inflow of 72.3~287.6 m3/d, supply water volume of water curtain of 45.5~232.7 m3/d, and in the operation, both parameters are predicted to be 323.5 m3/d and about 254 m3/d respectively.
