The authors consider that proper site selection in construction of underground water-sealing oil storage in rock caverns is very important.

According to hydrogeologic conditions and the design data of certain underground petroleum storage caverns and their water curtain systems,3D-numerical simulation models with and one without water curtain are created respectively to simulate the groundwater flow of the caverns using Visual MODFLOW.

Some problems of geologic hazard evaluation for underground water-sealed oil storage cave——Taking an oil storage cave in Shandong Province for example;

Fitting analysis of geo-stress field in Huangdao water sealed underground oil tank site

But the steel tank for storing gas, used for a hundred years, has not been apropos in dimension, cost and environment protection, so the underground water curtain grotto storage is emerged with practice.
