一种新型高温酸化缓蚀剂的制备及性能评价OA北大核心CSCDCSTPCD
Preparation and Performance Evaluation of a New High Temperature Acidizing Corrosion Inhibitor
目的 改善缓蚀剂在高温酸液中的缓蚀性能,满足油田高温井酸化施工的要求.方法 在合成一种新型吡啶季铵盐的基础上,添加炔醇、碘化钾等助剂进行复配,得到一种新型高温酸化缓蚀剂HTCI-1.使用HK-1高温高压动态腐蚀仪对其缓蚀性能进行测试,通过电化学测试、SEM、EDS等实验对其缓蚀机理进行分析.结果该酸化缓蚀剂在160℃、16 MPa、20%HCl或者土酸(12%HCl+3%HF)、质量分数3.0%的条件下,使N80试片的腐蚀速率分别为24.53 g…查看全部>>
The work aims to improve corrosion inhibition of corrosion inhibitor in high temperature acid liquor and meet requirement of high temperature well acidizing treatment. A new high temperature corrosion inhibitor HTCI-1 was obtained by compounding such additives as potassium iodide and potassium iodide in a newly synthesized pyridine quaternary ammonium salt. The corrosion inhibition was also tested by using high temperature and high pressure dynamic corrosion…查看全部>>
