The Creep Behaviour of Salt Rock Gas Cave under Cyclic Mining and Injection Pressure

Abstract:

In order to study the long-term deformation behaviour of salt rock gas storage at cyclic load, numerical method is adopted to simulate the salt mine at Hubei Yunying under the cyclic mining and injection pressure with maximum inter pressure of 20 MPa and minimum one of 2 MPa in ten years. As can be seen from the long-term simulation results, not only has the utilization of gas storage been reduced and has the wall rock of salt rock under cyclic loads continued to deteriorate. The test results provide both the basis for the safe and stable operation of the salt cave and a reference for the salt cave design of same type.
