摘要:

添加缓蚀剂可有效降低完井液的腐蚀性，而防止与控制完井液细菌污染和危害的方法主要有两类：通过改变环境条件（如提高完井液体系的ｐＨ值）使细菌难以生存。

Abstract:

All kinds of well completion fluid systems inherent more or less corrosive nature,and is easily polluted by bacteria thus leads to damage of the facilities.Adding corrosion inhibitor to well completion fluids can effectively reduce the corrosion.There are
