Scaling Mechanism of Produced Water Scaling Mechanism and Trend Prediction

In order to explore the scaling mechanism of produced water and predict the scaling trend, so as to further take anti scaling measures. This paper analyzes the scaling mechanism of produced water and its influencing factors from the aspects of ion composition in water, changes in thermodynamic conditions, crystal adsorption, etc., and introduces the scaling prediction methods commonly used at home and abroad, scaling prediction equations and simulation experiments for scaling prediction. The advantages and disadvantages of the fouling prediction method and the simulation experiment are compared and analyzed. Prospects are put forward for the development of fouling prediction methods and the optimization of simulation experiments. The development of fouling prediction methods and the optimization of simulation experiments are put forward. The work of scaling and cleaning is of great significance. The fouling prediction should consider many factors combining with the actual oil field; the fouling trend prediction method should be more accurate, more widely used, and more applicable.
