CO₂ Corrosion and Data Management of Metallic Well-logging Wires at High Temperature and High Pressure

According to the actual high temperature and pressure corrosion environment in Qinshen gas field,the common CO2 corrosion prediction model used for normal temperature and pressure conditions can not be used.CO2 corrosion test method in high temperature and pressure environment of Qinshen gas field was described.Based on the accumulated date of corrosion rate,a concept of establishing the database with the properties of graphical display,user-friendly query and quick prediction of corrosion rates was put forward.
