Abstract

The inhibitors based on nano-containing compositions (NCC) have been developed for hardness deposition. A method for developing an inhibitor for saline deposits involves the interaction of amino alcohols with orthophosphoric acid by adding nanoparticles and further diluting them with water to form a 2% solution. It was found out that the inhibitors developed by NSC for saline deposits at a flow rate of 20-30 mg/l are highly effective for controlling the deposits of calcium and magnesium sulfate in the produced water model. The controlling effect of inhibition in these cases is 86.3-99.4%. Keywords: inhibitor; amino-containing compound; orthophosphoric acid; hardness deposition; nanoparticles.
