    Abstract
  • In view of the problems of local corrosion, uniform corrosion and pipe body cracking of coiled tubing (CT) in formation containing CO2 and high-temperature and high-pressure gas well, the CT corrosion failure was investigated firstly, and the corrosion failure mechanism was analyzed. The numerical model of CO2 electrochemical corrosion of CT was established by COMSOL multifield coupling analysis method, and the influence of environmental factors on the corrosion rate was researched. The experimental result was compared with the numerical result. The result shows that the minimum error between the experimental corrosion rate and that of the numerical simulation is 1.3%. When the partial pressure of CO2 is 0.1, 0.5 and 1.0 MPa, the corrosion rate of CT reached its peak at 120, 90 and 60 ℃, respectively. When the partial pressure of CO2 is 0.1 MPa, and the electrolyte solution conductivity is 2.86, the corrosion rate of CT is higher at smaller pH value. This study is expected to provide suggestions for the safe use of CT in CO2 corrosion environment.
