Causes and countermeasures for scaling and corrosion in nitrogen gas injection wells

No.1 Oil Production Plant, SINOPEC Northwest Company, Luntai, Xingjiang 841600, China

摘要: 注氮气三次采油是油田开发中一种提高采收率的有效措施,但在注气作业过程中结垢腐蚀的发生给油气田开发过程带来了严重损失。通过分析注入介质对地面注入系统和井下管柱结垢腐蚀产生的规律及影响,表明在注入过程中混配地层水和注入氮气纯度较低是影响结垢腐蚀的主要因素。通过提高注入氮气纯度、非金属材料和牺牲阳极材料的应用能降低系统结垢腐蚀发生速率。

Abstract: Nitrogen gas injection in the third round of oil recovery is an effective way to improve recovery rate; however, scaling and corrosion bring serious oil development losses. The influence of injection agent on ground injection system and downhole strings was analyzed. The mixing of formation water and the low purity of nitrogen gas are the main causes for scaling and corrosion. We can reduce scaling and corrosion rates by using purer nitrogen gas, non-metallic materials and sacrificial anode materials.
