Water seal effect of an underground crude oil storage caverns is the key to the normal operation. This paper analyzes the monitoring data of the water level of water curtain, supplementary water capacity of water curtain, ground water, pore water pressure of main cavity, seepage volume of main cavity, temperature of main cavity collected in the trial production of underground crude oil storage caverns. According to the data analysis, the timely water supplement of water screen system ensures
more » ... t the water level of water curtain in the normal operation reaches the lowest hydraulic boundary, which proves the water seal effect is reliable. And the independence of water seal resistance between main cavities is poor, and the liquid pressure difference and pressure difference should be decreased as far as possible.
