To better understand hydrate-slurry flow, a series of experiments wasperformed, including water, natural gas, and diesel oil, under 4-MPa systempressure and 1.25-m/s initial linear velocity. The experiments have beenconducted in a high-pressure hydrate-flow loop newly constructed at ChinaUniversity of Petroleum (Beijing), and dedicated to flow-assurance studies. Afocused-beam reflectance measurement (FBRM) probe is installed in this flowloop, which provides a qualitative chord length distribution (CLD) of theparticles/droplets in the system. First, the influence of flow rate on thehydrate-slurry flow was discussed. Then, we studied other influencingfactors--such as water cut and additive dosage--on the hydrate induction periodand the CLD before/after hydrate formation. Third, a new correlation was fittedbetween the dimensionless rheological index n' and water cut as well asadditive dosage, according to these experimental data. Finally, a laminar-flowmodel for the prediction of the pressure drop for the quasisingle-phase hydrateslurry was established, and tested by comparison with the experimental resultsin this paper.
