摘要:

由水合物生成与聚集引起的堵塞一直是深水油气流动安全保障领域面临的棘手问题。水合物阻聚剂(AAs)因可防止水合物颗粒聚集而成为降低水合物风险的有效方法之一。本文基于作者课题组在水合物抑制技术方面的研究工作,分别梳理表面活性剂型和固体颗粒型水合物阻聚剂的构效关系。同时,调研国内外宏观-微观-分子不同尺度的阻聚性能测试手段,包括高压搅拌反应釜、摇摆槽、流动轮和流动环路,以及微观力测试仪和分子动力学模拟。基于上述实验装置和分子模拟研究结果,总结了不同类型阻聚剂对水合物的作用机理,特别是乳化和吸附机理。最后分析现有水合物阻聚剂存在的问题,并展望了水合物阻聚剂的未来发展方向。这为将来适用于南海深水油气田的高效、绿色和经济水合物AAs的开发提供重要的技术支持。

Abstract:

The blockage caused by hydrate formation and deposit is always a troublesome problem threatening deepwater oil and gas flow assurance. One effective way to mitigate the hydrate risk is injecting hydrate anti-agglomerants (AAs), due to their capability of inhibiting hydrate particles aggregation in oil-water systems. Based on the work of our research group on hydrate inhibition technology, the structure-activity relationship of surfactant- and solid particle-based AAs was reviewed, respectively. At the same time, performance test methods at macro, micro and molecular scales were investigated, including high-pressure stirred reactor, rocking cell, flow wheel and flow loop, micromechanical force apparatus and molecular dynamics simulation. According to the above experimental setups and molecular simulation results, the action mechanism of different types of AAs on hydrates, especially emulsification and adsorption mechanism, was summarized. Finally, the existing drawbacks of hydrate inhibitors were analyzed, and the future development of the aspect was prospected. It will provide important guidance for the design of efficient, green and economical hydrate AAs suitable for deepwater oil and gas fields in the South China Sea in the future.
