在我国,油田的油气伴生水和回注水对采油设备,集输管线的腐蚀是十分普遍的。每年因此而造成的经济损失十分巨大。目前,国内已有一些缓蚀剂用于抑制油田污水对设备的腐蚀,取得了一些好的效果。但是,由于我国油田的地质构造不同,各区块、各岩层的地下水质差异比较大,引起腐蚀的原因也就变得非常复杂。 In China, the oil and gas associated with the oil and water injection on the oil recovery equipment, gathering pipe corrosion is very common. The economic loss caused by this is huge every year. At present, some domestic corrosion inhibitors have been used to suppress the corrosion of oilfield sewage on equipment and some good results have been achieved. However, due to the different geological structures of oilfields in our country, the groundwater quality of each block and each rock formation is quite different, and the cause of corrosion is also very complicated.
