摘要:

天然气水合物是一种绿色化石能源,但是在石油和天然气开采、管道运输过程中,管道内形成的水合物会聚集堵塞管道,对油气管道安全储运带来严峻挑战。首先,本文结合国内外关于防治水合物成核与聚集的实验和分子模拟研究成果,介绍了不同运输体系中天然气水合物成核、聚集过程以及影响因素,回顾了传统防治天然气水合物成核与聚集方法及其利弊。其次,阐述了特殊浸润性材料基本概念以及在油气相关领域的应用,并着重梳理了其在抑制天然气水合物成核与防止天然气水合物黏附聚集管壁等方面的研究进展。分析了不同运输体系中特殊浸润性材料在应对天然气水合物成核与聚集应用过程中存在的挑战,并对其提出针对性解决设想。最后,对特殊浸润性材料应对水合物成核与聚集领域的未来发展趋势进行了展望。

Abstract:

Natural gas hydrates are a green fossil energy source, however, during oil and gas extraction and pipeline transportation, the formed hydrates can plug pipeline, posing a serious challenge to the safe storage and transportation of oil and gas pipelines. In this article, we outline the research process and influencing factors of hydrate nucleation and aggregation in different transport systems, and reviews the traditional methods of preventing and managing the nucleation and aggregation of natural gas hydrate and their advantages and drawbacks. Then, the fundamental principles of special wetting materials and their applications in oil and gas related fields were elaborated, and their research progress in inhibiting the nucleation of natural gas hydrates and preventing their adhesion and aggregation to pipe walls was highlighted. The challenges of special wetting materials in various transportation systems in addressing the nucleation and aggregation of natural gas hydrates are discussed, and focused solutions are suggested. Finally, we outlook the future development trend of special wetting materials in the field of preventing hydrate nucleation and aggregation.

Key words: special wettability, nanomaterials, hydrate, nucleation, agglomeration
