Abstract: Casing damages during injecting well blowout have taken place commonly in many oil fields in China. In order to study the mechanism of the casing damage, fluid-solid coupled model to simulate casing stress and deformation is established; the numerical simulation based on the finite element method is also given. The simulation results show during the blowout process, the geo-stress around well-bore changes. At the beginning of the blowout, the tangent and radial stresses are big. The simulation results are very helpful to the casing protection in oil fields.

Key words: fluid-solid coupling, casing, blowout job, finite element method, water-injecting well
