Analysis and Optimization of Bowl Skeleton

Abstract

In the process of oil development operations, the sealing bowl is adopted to seal the drilling fluid in the well. It relies on the interference between the bowl and the casing to achieve the sealing function. And the skeleton can significantly improve the bearing capacity of the sealing bowl. However, sealing bowls with different kinds of steel skeletons have huge differences in the sealing function. In this paper, by using ANSYS Workbench to establish the bowl model and optimizing the skeleton structure parameters, we can get the optimal skeleton form that meets the requirement of sealing pressure 35MPa.
