Use salt rock underground caverns to store gas is an important storage mode in China, effective risk management is the key to the success of this method. Aimed to risk management, a risk management system was designed and developed, at first, overall framework of the system was designed, and then, each module was detailed designed, the risk evaluation mode was built. Application of this system can effective monitoring risk of salt rock underground gas caverns, greatly improve the level of security.

Use salt rock underground caverns to store gas is an important storage mode in China, effective risk management is the key to the success of this method. Aimed to risk management, the foundation work is risk assessment. Fuzzy math is an effective method for solve uncertainty problem just like risk assessment. In this article, a salt rock underground gas caverns risk assessment model based Fuzzy Math was built, with this model, the risk level of salt rock underground gas caverns can be quantitatively evaluated, and the evaluation results can be used as a reference for risk rescue decision.
