多相混输管道内水合物形成过程研究进展

Review on the Formation of Gas Hydrate in Multi- phase Flow Pipeline

针对由水合物造成的管道堵塞,特别是油-气-水多相混输领域水合物堵塞尤为严重的问题,系统调研了水合物在多相混输管道内形成机理的研究进展,着重介绍了富油相/富水相和富气相两个体系;基于水合物颗粒微观作用机理,详细阐述了水合物颗粒间的黏聚和水合物颗粒与管壁间的黏附作用;指出了多相混输管道内水合物形成过程的未来研究方向。

This paper first investigated the progress on the gas hydrate formation mechanism in multi -phase flow pipelines, including oil - dominated/water - dominated and gas -dominated systems. Next, based on the microscopic mechanism of gas hydrate parti- cles, the review on adhesion/cohesion forces between hydrate particles was introduced in detail. Finally, the major targets of researching work in the future were also proposed in this paper.
