Abstract
In this work, the fatigue analyses of cement bridge plug under different oil-gas well conditions are performed. By using the state-of-the-art modelling framework by application of SolidWorks and ANSYS Workbench finite element softwares, the three-dimensional models of cement, bridge plug and casing with consideration of three different materials is explored and analyzed. The analysis shows that there are tensile stress concentrated in the area of connection between slips and cones of bridge plug. This finding in terms of safety factor reveals that considered bridge plug structures are safe against fatigue under most working conditions but it tends to fail when it comes to high pressure and high temperature (HPHT) condition as expected.
