钻井液抗氧缓蚀剂CT2—13在川东气田的应用

APPLICATION OF OXYGEN CORROSION INHIBITOR CT2-13 IN EAST SICHUAN GAS FIELD

摘要: 现场钻井液对钻具具有较强的腐蚀作用，腐蚀速率达到1mm/a以上。缓蚀剂CT2－13是一种性能优良的钻井液抗氧缓蚀剂，与现场钻井液配伍性好，可将钻具腐蚀速率控制在0.3mm/a以下。缓蚀剂CT2－13适用于聚合物、聚合物低固相、聚磺钻井液中溶解氧腐蚀防护,可应用于深井作业。

Abstract: Dissolved oxygen in field drilling fluids will corrode drill tools severely.Corrosion rate of G105 steel can reach about 1mm/a.In order to control oxygen corrosion in field drilling fluids,corrosion inhibitor CT2-13 is added to field drilling fluids and i
