Material Selection of Casing in Gas Well Containing CO2 and H2S
Based on analysis of different guidelines and standards for material selection of casing which belong to six companies in four countries, the main factors that influence the material selection of casing have been generalized. Through comparing the safety and corrosion resistance properties of materials recommended by different guidelines in specific conditions, a synthetic guideline has been developed, which can provide a more appropriate suggestion. The environmental conditions and materials adopted in East Sichuan region have been taken for example. By comparing the proposed results with adopted materials of field well completion, it demonstrates that the result provided by the synthetic guideline is accurate and reliable.
