多相混输管道水合物防控技术及现场应用研究进展

Review on Gas Hydrate Prevention and Control Technology and Field Application in Multi-phase Flow Pipeline

由水合物造成的管道堵塞问题长期困扰着油气生产和运输部门,特别对油-气-水多相混输领域,水合物问题尤为严重。首先系统调研了国内外水合物防控技术的研究进展,着重介绍了低剂量水合物抑制剂的最新研究成果;其次详细阐述了低剂量水合物抑制剂在现场油气田的应用情况;最后指出了水合物防控技术未来的研究重点。

The problem of hydrate blockage of pipelines which has plagued for a long time becomes more and more severe for oil and gas industry. Therefore,the progress on the gas hydrate inhibition technology in multi- phase flow pipeline was investigated focusing on the development of low- dosage hydrate inhibitor. The field application of low-dosage hydrate inhibitor was introduced in detail. The major targets of researching work in the future was also proposed.
