1前言缓蚀剂是油田采油、注水、酸化等生产过程中广泛使用的防腐药剂,是油田生产中使用率最高的一种油田化学剂,“缓蚀率”是评价缓蚀剂使用性能的主要指标。目前,各个油田评价缓蚀剂的缓蚀率检测采用的是石油行业标准SY/T5273《油田采出水用缓蚀剂性能评价方法》。在进行缓蚀 1 Preface Corrosion inhibitor is a widely used anti-corrosion agent in oilfield production, water injection, acidification and other production processes. It is a kind of oilfield chemical with the highest utilization rate in oilfield production. The “corrosion inhibition rate” is the main factor to evaluate the performance of corrosion inhibitor index. At present, all oilfields evaluate the corrosion inhibition rate of corrosion inhibitor used in the oil industry standard SY / T5273 “performance evaluation method of oil field produced water corrosion inhibitor.” Corrosion in progress
