Abstract
In this paper, calculating the deformation and the static strength of the fluid channel during the process of casing hanger running, well cementation and oil production with ANSYS. Researching the effect of the fluid channel deformation on drain and decompression, and the effect of the fluid channel stress concentration position and its existence on casing hanger structure strength. On the basis of those research, ascertaining the optimum range of the fluid channel aperture.
