Effect Evaluation of Inhibitor to Barium Sulfate and Strontium Sulfate

Abstract:

Facing at the situation that a large amount of BaSO₄/SrSO₄, which seriously impacts on oil production operation scale, has been yielded during oilfield production, three kinds of scale inhibitor (TS-09, TH-60 and PBTCA) were collected from oilfield for comprehensive evaluation. The results show that the three kinds of scale inhibitor have certain scale inhibition effect to BaSO₄/SrSO₄, and the influence of different water quality is obvious. When TH-60 concentration was 100 mg/L, its inhibition rate to BaSO₄ has reached 95%. In comparison, scale inhibition effect of TH-60 to BaSO₄/SrSO₄ is better than the others. TH-60 is more suitable for Huaqing oilfield than TS-09 and PBTCA, concentrations range in 100-180 mg/L especially.
