Abstract According to the principles of underground gas-storage caverns with water curtain，variational principle in LPG coupling system of stress field，seepage field and gas-storage field of underground gas-storage caverns is established and its FEM program is developed. The programs are applied in engineering，and the numerical model is proved to be reasonable and credible.

Key words： geology of petroleum and natural gas underground water sealed gas-storage caverns coupling model variational principles
