Abstract
The study is based on the mechanical model of soil-cement ring-casing and uses the finite element software
ANSYS. We select a certain combination of loads, study the situation of ideal round casing and ideal round cement ring
combination, the situation of Ideal round casing and oval cement ring combination, and the situation of initial elliptical
bushing and elliptical cement ring combination. In addition, we obtained the stress distribution of each part in different
cases .It is concluded that the existence of casing ellipticity and the presence of cement ring will greatly affect the
distribution of stress values of casing, cement ring and formation, and will affect the maximum size and appearance of
each part s position.
