油气田开发过程中的缓蚀剂应用
|
摘要
在油气田开发过程中,金属腐蚀是一个较为严重的问题。缓蚀剂的使用能有效抑制管道和设备腐蚀速率,但由于缓蚀剂种类繁多,作用机理复杂,适用条件不同,使得正确筛选合适缓蚀剂存在困难。介绍了缓蚀剂目前主流机理模型,分别给出了油气井缓蚀剂、酸化缓蚀剂、油田污水缓蚀剂和酸洗缓蚀剂常用类型。结合油气田缓蚀剂评价与筛选标准可以准确筛选出适用于当前环境下的缓蚀剂。
Metal corrosion is a more serious problem in the development of oil and gas fields. The use of corrosion inhibitor can effectively inhibit the corrosion rate of pipelines and equipments. However, due to the variety of corrosion inhibitors, complex mechanism of action and different applicable conditions, it is difficult to properly screen suitable corrosion inhibitors. In this paper, current mainstream mechanism models of corrosion inhibitors were introduced, and the common types of corrosion inhibitors, acidification inhibitors, oilfield sewage corrosion inhibitors and pickling inhibitors were given. Combined with the evaluation and screening criteria of oil and gas field corrosion inhibitors, how to accurately screen the corrosion inhibitors suitable for the current environment was discussed.
