Failure analysis for gas storage salt cavern by thermo-mechanical modelling considering rock salt creep
Abstract
Salt cavern is ideal vessel for underground gas storage due to the high deliverability. During cyclic gas operations of injection-and-withdrawal, the temperature change in salt cavern imposes thermal stress on cavern wall. The temperature change, together with the pressure change in salt cavern, causes the effective stress on cavern wall to alter, leading to variation of creep rate. In this study, a coupled thermo-mechanical model is proposed...
