颗粒团聚在天然气水合物聚集和管道堵塞机理中起着重要作用。天然气水合物是天然气包裹在三维水晶格中形成的固体包裹体化合物，可在石油流动管线中形成并阻碍流体传输。团聚机制是复杂的，但必不可少的创建可靠和准确的流变模型，优化流体流动操作，其中的国家的最先进的包括接触诱导和剪切诱导团聚模型。可以使用原位聚焦光束反射测量（FBRM）和粒子视频显微镜（PVM）探针或其他类似工具来进行油连续相中反应以随时间形成气体水合物附聚物的水滴的粒度分布测量。颗粒尺寸测量和界面相互作用测量是天然气水合物流体动力学多相流模型的基础，该模型结合了颗粒团聚/粘度模型和基于毛细管桥理论的内聚力模型，原位颗粒尺寸测量探针也可以作为天然气水合物形成起始的辅助过程指示器。为了开发和验证准确的天然气水合物团聚模型，必须进行原位颗粒尺度实验，这是最先进的水合物流动保证建模和风险评估不可或缺的。
Particle agglomeration plays a major role in the mechanism of gas hydrate accumulation and pipeline plugging. Gas hydrates are solid inclusion compounds composed of natural gas trapped in a three-dimensional water lattice that can form in petroleum flow lines and impede fluid transfer. Agglomeration mechanics are complex yet essential to creating reliable and accurate rheological models for optimizing fluid flow operations, of which the state-of-the-art includes the contact-induced and shear-induced agglomeration models. Particle size distribution measurements of water droplets in an oil-continuous phase reacting to form gas hydrate agglomerates over time can be performed usingin situfocused beam reflectance measurement (FBRM) and particle video microscope (PVM) probes, or other similar tools. Particle sizing and interfacial interaction measurements form the basis of gas hydrate hydrodynamic multiphase flow models, which incorporate particle agglomeration/viscosity models and the capillary bridge theory-based cohesion model.In situparticle sizing probes can also serve as a supplementary process indicator of gas hydrate formation onset. It is essential to performin situparticle-scale experiments to develop and validate an accurate gas hydrate agglomeration model, which is integral to state-of-the-art hydrate flow assurance modeling and risk assessment.
