用于CO 2注入井的典型材料是耐腐蚀合金(CRA) 或环氧树脂内衬管。目前应用最广泛的CRA材料是25Cr，其应用成本较高。将25Cr以外的材料应用于CO 2注入井并不常见，但可能适合其用途。完整的论文描述了在 K1 油田 CO 2封存项目中使用 25Cr 以外的材料进行的材料选择方法和腐蚀研究，目的是在不损害 CO 2注入井完整性的情况下优化油井成本并提高整体项目经济性。
K1油田位于砂拉越盆地，水深453英尺。
Typical materials used for CO2 injector wells are either corrosion-resistant alloys (CRA) or epoxy-lined tubulars. The most widely adopted CRA material is 25Cr, which features a high well-application cost. Application of materials other than 25Cr for CO2 injector wells are uncommon but may be fit for purpose. The complete paper describes material-selection methodology and corrosion studies performed in the K1 field CO2 sequestration project using materials other than 25Cr in an effort to optimize well costs and improve overall project economics without jeopardizing CO2 injector-well integrity.
K1 field is in the Sarawak Basin at a water depth of 453 ft.
