摘要

摘要与盐酸相比,有机酸能降低高温储层酸化中酸岩反应速率。虽然缓蚀剂可以减少酸对管柱的腐蚀,但超高温使缓蚀剂的效果不理想。我们发现纳米二氧化硅的使用可以提高有机酸体系中缓蚀剂的有效性。下面是一些有趣的发现。首先,超高温使LD-H吸附膜不均匀或不完整。其次,在有机酸中加入纳米二氧化硅,增强了缓蚀剂的高温缓蚀能力,缓蚀率高达99%。此外,纳米二氧化硅的加入使LD-H吸附膜更加完整或均匀,更有效地抑制了腐蚀反应。纳米二氧化硅通过增强缓蚀剂的吸附能力和填充吸附膜,增强了LD-H在有机酸体系中的缓蚀效果。关键词:纳米材料;超高温;协同缓蚀;披露声明作者未报告潜在的利益冲突。竞争利益声明作者声明,他们没有已知的竞争经济利益或个人关系,可能会影响本文所报道的工作。信用作者贡献声明杜鹃:构思,监督。,资源,写作-审查和编辑。李策:方法论,软件,验证,写作-原稿。刘平利:项目管理。刘金明:写作-评论与编辑。向晨:概念化。王冠:概念化。左子轩:可视化。黄成喜:调查。楼凤成:调查。王明:调查。本研究得到中石油-西南石油大学创新联盟科技合作项目(2020CX0105)资助:[批准号]。

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.
