本文围绕新型水合物化学抑制剂（防聚剂）在海上油气田现场应用过程中将遇到的管道输送工艺设计技术问题开展研究。首次以海上凝析油气田现场采集的油、水和按天然气组分配置的气体为实验介质，加入国内自主研制的水合物防聚剂，在水平透明实验环道上进行了水合物浆液流动压降实验。通过分析实验结果并借助液固两相流有关理论，初步建立了水合物浆液管输压降计算方法。针对某管线的实际运行条件，借助OLGA软件进行计算分析，结合上述压降计算方法，计算出使用防聚剂时管线的压降，为防聚剂的现场应用提供支持。
When new types of hydrate chemical inhibitor （such as hydrate anti-agglomerant） are used in offshore fields, some difficulties will be encountered in the pipe transportation processing design. In view of these difficulties, a horizontal flow experiment pipe loop of transparent polypropylene pipes constructed, and some experiments were conducted. The working fluids are the mixed paraffin hydrocarbons, water and condensate oil mixtures obtained from offshore oil field. Analyzing the experimental results and adopting relevant theories of liquid-solid two-phase flow, the computational method of hydrate slurry transportation in pipe has been developed. For the operating conditions of a certain multiphase pipeline, by using OLGA software, this method can be used to calculate pressure drops of the multiphase flow pipelines using anti-agglomerant. Which can provides support for hydrate anti-agglomerant application.
