Three-dimensional seepage analysis of underground LPG storage with water curtain

The airproof condition of underground gas storage with water curtain is presented in this paper. Three dimensional numerical seepage analysis was carried out on the liquefied petroleum underground gas storage in China, and the function of water curtain and influence to around seepage field was considered. The analysis gives a good proof that using water curtain to storage LPG in underground is safe. It will provide quite valuable reference for the design and construction of gas storage cave in China.
