  • The safety of underground salt cavity gas storage is the key geological problem of gas storage operation. The Pingdingshan salt field is characterized with thin layers, multiple interlayers and deeply buried layers. Its geological storage feasibility and ground settlement are studied using the permeability, rheology and stability of layered salt rock. First, the pure salt rock, layered salt rock and mudstone interlayer samples are collected. Then electronic microscope scanning and triaxial compression creep experiments are conducted. Then the salt rock cavities are detected by CYT method. Field monitoring shows that ground settlement is small and fluctuating because some influence zones of mining wells are overlapped. Based on the geological characteristics of study area, it can be concluded that the geological conditions of Pingdingshan underground salt cavity gas storage are favorable, and also can provide some references for similar projects in China.
