Numerical Simulation of Influence of Different Time of Shutdown on Casing Stress in Thermal Recovery Well
The influence of different time of shutdown on casing stress in thermal recovery well was studied by numerical simulation based on theory of Thermal-Mechanical coupling. The simulation results shown that the longer the time of shutdown, the greater the decline in value of casing stress, then the casing stress was greater when continuing to inject steam to the stabilized state of the casing, so the shutdown had greater impact on casing security. The simulation results are very helpful to choose a reasonable time of shutdown and the casing protection in oil fields.
