Abstract:
The state of carbon dioxide and its effect on corrosion of pipe string for the oil and gas well at high temperature and pressure were theoretically analysed. A new theoretical conception was presented, in which the carbon dioxide mole concentration in the system and its distribution coefficient in the medium of oil and water in the condition of total pressure were defined to describe corrosion purarox te deep stratum and pressure funnel in pipe string when carbon dioxide is in the supercritical fluid state.
Key words: CO2 corrosion, high pressure and temperature, supercritical fluid, CO2 corrosion film
