Oilfield water contains a large amount of metal ions such as calcium and magnesium,which are prone to form scale in high-temperature and high-pressure environments.
Scale will adhere to the surfaces of oil well pipelines, pumps, valves, and other equipment,leading to a decrease in equipment efficiency and even malfunctions.
Scale inhibitors can reduce the possibility of these ions forming scale through chelation, thereby protecting equipment from scale damage; Effectively preventing the formation of scale and maintaining the smoothness of oil wells can help increase crude oil production;It can significantly improve the efficiency of oilfield water treatment and reduce the problem of formation and pipeline blockage. The use of scale inhibitors can also extend the ser
vice life of equipment and reduce maintenance costs.
