摘要
由水合物生成及聚集引起的管道堵塞是深海油气流动保障面临的主要问题之一。水合物阻聚剂（AAs）可通过阻止水合物颗粒聚集从而防控水合物堵塞，具有使用剂量低、适应高过冷度（> 10 ℃）环境等优点，应用前景广阔。首先综述了不同类型的水合物阻聚剂，从分子尺度分析了阻聚剂在水合物表面的作用机理，以及阻聚剂构象对其性能的影响；然后总结了常用的阻聚剂评价设备及评价方法，并探讨了体系中液烃组成、含水率、蜡、沥青质，以及盐等其他物质对阻聚剂阻聚效果的影响；最后展望了水合物阻聚剂的未来发展。水合物阻聚剂在体系中的作用机制是复杂的，可根据不同体系选择适应性与阻聚效果更好的阻聚剂。本研究可为开发高效、绿色、经济的水合物阻聚剂提供参考。
Abstract
Pipeline blockage caused by hydrate formation and aggregation is one of the major challenges in deep-sea oil and gas flow assurance. Hydrate anti-agglomerants (AAs) can prevent hydrate particle aggregation
thereby mitigating hydrate blockage. Anti-agglomerants have advantages such as low dosage requirements and suitability for high subcooling environments (> 10 ℃)
making them promising for future applications. First
the different types of hydrate anti-agglomerants were reviewed
and the mechanisms of action of the anti-agglomerants at the molecular level on hydrate surfaces were analyzed
and how the conformation of the anti-agglomerant influences its performance was discussed. Then
common evaluation equipment and methods for anti-agglomerants were summarized
and how factors such as the composition of liquid hydrocarbons
water cut
waxes
asphaltenes and salts affect the anti-agglomeration effect was explored. Finally
the future development of hydrate anti-agglomerants was prospected. The mechanism of action of anti-agglomerants in the systems is complex
and the anti-agglomerants with better adaptability and inhibition effect can be selected according to different systems. This study can provide a reference for the development of efficient
green and cost-effective hydrate anti-agglomerants.
