Abstract
A water-sealed system affects the normal usage of an underground oil storage cavern. To make sure that the water seal is in good condition, continuous tunnel water inflow is needed. A reasonable tunnel water inflow is larger than local seepage and smaller than unlimited water flooding. Different shaped tunnels have various water inflows in the same working conditions. Different working conditions also may lead to different water inflows. The FEM (finite element method) software ANSYS thermal module can accurately simulate the underground inflow of various shaped tunnels or various working conditions. Results show that tunnel shape affects inflow less than 12% and operating conditions' inflow is about 24% less than that of construction conditions.
