介绍了镁合金(MB_2)用作CO_2EOR地下管柱封隔器以下部位的油/套管的牺牲阳极保护的研究。用电化学方法测量镁合金与J_(55)钢之间的电偶电流,用失重法测定镁合金与J_(55)钢之间的电偶腐蚀,为井下环形空间井管用镁合金牺牲阳极保护提供了合适的比例。
The sacrificial anode protection of magnesium alloy (MB_2) as oil / casing below CO_2EOR underground string packer was introduced. Galvanic current between magnesium alloy and J_ (55) steel was measured by electrochemical method. Galvanic corrosion between magnesium alloy and J_ (55) steel was measured by weight loss method. Magnesium alloy sacrificial anode protection Provide the right ratio.
