Research progress in oil-field scale prevention techniques

The presence of scaling poses significant issues in the production and recovery benefits of oil fields. This article reviews the causes of oilfield scales and elaborates on common scale prevention methods, including chemical technique, ultrasonic technique, electromagnetic technique, and metal coating technique. The paper describes the existing techniques in detail, lists their respective advantages and disadvantages, and proposes a technology variation that can reduce the formation of scales. This work is expected to contribute guidance in normal oil field production.
