Abstract
This of article is devoted to solving the problem of determining the actual mechanism of corrosion caused by the influence of corrosive environment with high pressures and temperatures on the tubing pipe metal, during high depth condensate fields development, with a high content of hydrogen sulfide and carbon dioxide in the fluid. The of results of the actual state evaluation of tubing pipe specimens are presented, the causes and nature of the corrosion damages and the mechanisms of their progress in the given conditions are identified. In particular, the of results of visual and instrumental investigation shows, that corrosion of the tubing surface has local (zone) nature; corrosion processes occurs as on interior as well on exterior tubing surface, whereby interior surface has the presence of corrosion deposits in local zones and also pitch zones, and exterior surface corrosion is present only by pitch corrosion. The local corrosion on the tubing surface is caused by carbon dioxide carrion. The main impact factor is the presence in gas-liquid mixture the molecules of СО2 and Н2СО3 and ions НСО3- and HСО32-, as a result of carbon dioxide gas dissolving, which activate the environment corrosive aggressiveness.
