Abstract

The wellbore chemical anti-scaling technology is one of the effective ways to enhance the maintenance time of pump in the ASP flooding. This study investigated the different amount of calcium ion, silicon ion and scale inhibitor influenced the anti-scaling performance of the simulation system. The result indicated that the anti-scaling rate decreased when the content of calcium and silicon increased and the best concentration of scaling inhibitor existed. When the silicon content was 150 mg×L-1 or less, it could not influence the anti-scaling performance of scale inhibitor. When the content of calcium ion was 10-80 mg×L-1, the concentration of scale inhibitor increased with the increase of calcium ion content. There is a functional relationship between the calcium and scale inhibitor. According to empirical formula, the amount of scale inhibitor in the single well can reduce more than 20% and the average amount saved 31.05%.
