Calcium alginate gel capsules loaded with inhibitor for corrosion protection of downhole tube in oilfields
Source abstract
Abstract
Abstract Calcium alginate gel (Alg-Ca 2+ ) capsules loaded with inhibitor and heavy additive were prepared by a piercing-solidifying method. The releasing process of inhibitor together with their inhibitive effect on P110 steel in CO 2 -saturated 3.5 wt.% NaCl aqueous solution was investigated by ultraviolet–visible spectrophotometer, scanning electron microscopy, electrochemical impedance spectroscopy. Our experiments revealed that the synthesized capsules can gradually release inhibitors during their sinking process, and effectively prevent the tube in oilwell from corrosion. Introducing appropriate amount of heavy additive BaSO 4 into the inhibitor-loaded capsules facilitates their sinking processes and corrosion protection performance.
