Research on the Scale Inhibition Performance of AA/MA/MAC Copolymer

Abstract:

The terpolymer was synthesized by maleic anhydride (MA), acrylic acid (AA) and methyl acrylate (MAC) and the structure was also conformed. Its scale inhibition effect was also studied in high barium and strontium ion concentration aqueous medium and simulated formation water (Ca2+, Mg2+, Ba2+, Si2+) condition. The results indicate that when additive amount of AA/MAC/MA is 60 mg/L, the inhibition rate is up to 100% and 80% for BaSO4 scale and SrSO4 scale respectively, but only 50% for calcium scale. And the scale inhibition rate moderately increases with the dosage increasing. The scale inhibition effect of AA/MAC/MA is also very obvious in simulated formation water containing low calcium ions (400 mg/L) and high barium ions (500 mg/L) as well as strontium ions (500 mg/L). It can satisfy the need of restraining composite scale (BaSO4 scale and SrSO4 scale as well as CaSO4 scale) in high calcium and barium strontium ion aqueous medium when compounded with calcium scale inhibitors CY and CX respectively.
