Inhibition effect of nano-silica synergistic corrosion inhibitor on 110SSsteel in ultra-high temperature organic acidic environment
ABSTRACTCompared to hydrochloric acid, organic acids can reduce the acid rock reaction rate in high-temperature reservoir acidification. Although corrosion inhibitors can reduce the corrosion of acid on the pipe string, the ultra-high temperature makes the effectiveness of corrosion inhibitors unsatisfactory. We found that the use of nano-silica can improve the effectiveness of corrosion inhibitors in organic acid systems. Some interesting findings are as follows. Firstly, the ultra-high temperature made the adsorption film of LD-H uneven or incomplete. Next, the high-temperature corrosion inhibition ability of corrosion inhibitors was enhanced by adding nano-silica to organic acids, with a corrosion inhibition rate of up to 99%. Furthermore, the addition of nano-silica made the adsorption membrane of LD-H more complete or uniform, which more effectively inhibited corrosion reactions. By enhancing the adsorption capacity of corrosion inhibitors and filling adsorption membranes, nano-silica enhanced the corrosion inhibition effect of LD-H in organic acid systems.KEYWORDS: Nanomaterialultra-high temperaturesynergy corrosion inhibitionorganic acid110SS steel AcknowledgementsThis work was supported by Science and Technology Cooperation Project of the CNPC-SWPU Innovation Alliance (2020CX0105).Disclosure statementNo potential conflict of interest was reported by the author(s).Declaration of competing interestThe authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.Credit authorship contribution statementJuan Du: Conceptualization, Supervision., Resources, Writing – Review & Editing.
