Pear-shaped casing swage (PCS) repair technology is highly efficient in repairing deformed casing and the value of repairing force is a very important parameter for designing and optimizing the casing swage and structure parameters. A new three-dimensional simulation analysis of casing swage in the well and the finite element analysis (FEA) model of 7′′ API deformed casing and PCS are established based on the elastic-plastic mechanics, the finite element theory, and application of numerical simulation analysis for the actual process of repairing deformed casing. According to the model, the repairing force required to repair the deformed casing is obtained; furthermore, the correlation between the repairing force and confining pressure is obtained. Meanwhile, the repairing test of deformed casing was performed by using PCS in the lab. Experimental results are consistent with simulation results. It indicated that the mechanical model can provide theoretical guidance for design and optimization of the structure of tool and reshaping technological parameters. |
