Performance and characteristics
In the process of oilfield development, it is necessary to inject water into the stratum to remove oil and replenish energy for the formation. Because the injected water contains salt and dissolved oxygen, it is corrosive to the water injection equipment, pipelines and pipe posts, and corrosion inhibitor is necessary to be added to reduce corrosion. A good corrosion inhibitor should have good corrosion suppression performance, good solubility, cheap price and low toxicity.
