Petroleum and natural gas industries. Materials selection for high content CO<sub>2</sub> environment for casings, tubings and downhole equipment
石油和天然气工业 套管、油管和井下设备用高含量CO<sub>2</sub>环境的材料选择
This International Standard provides guidelines and requirements for material selection of both
seamless casing and tubing, and downhole equipment for CO2gas injection and gas production wells
with high pressure and high CO2content environments [higher than 10 % (molar) of CO2and 1 MPa CO2partial pressure]. Oil production wells are not covered in this International Standard. This International
Standard only considers materials compatibility with the environment.Guidance is given for the following:corrosion evaluation;materials selection;corrosion control.This International Standard is aimed at high CO2content wells, where the threat of low pH and CO2corrosion is greatest. However, many aspects are equally applicable to environments containing lower
CO2concentrations.Materials selection is influenced by many factors and synergies and should be performed by either
materials or corrosion engineer.Cross References:ISO 11960ISO 13680ISO 15156ISO 21457ISO 23936-1ISO 23936-2ISO 14310ISO/TS 16530-2ASTM D790ASTM D2290ASTM D2344ASTM D2583API 5LD 2009API RP 15CLTISO 17078-1:2004All current amendments available at time of purchase are included with the purchase of this document.
