Abstract

In the present work ,according to the present situation that casing pipe are frequently applied in the high temperature environment containing hydrogen sulfide and carbon dioxide, degradation of mechanical properties of casing pipe in the environment with hydrogen sulfide and carbon dioxide is also investigated in the paper. The results show that degradation of mechanical properties of casing pipe is serious, the biggest decreased degree of P110S and P110 are 13.71% and 13.02% respectively. It is considered through analysis that the main reason of degradation of casing pipe in the Carbon dioxide environment is related to the localized corrosion on the steel surface. The degradation of mechanical properties of carbon steel is analysed with the relations between elastic modulus and hydrogen effects on atomic binding force in this paper.
