Abstract
Integrated prediction models on injection-production operation of Salt cavern underground gas storage are built. Simulation prediction research on performance of cavern and wellbore is presented in emergency operation, normal peak load operation, stable operation and intermittent operation modes. The results show that cumulative production gas volume is most in normal peak load operation mode, but cumulative production gas volume is least in stable operation mode. Cumulative injection gas volume is most in emergency operation and normal peak load operation mode, but cumulative injection gas volume is least in intermittent operation mode. At the same time, long-term emergency operation and intermittent operation will be avoided for guaranteeing good operation characteristic of salt cavern gas storage.
