Pressure prediction in deep-water pipeline considering formation of natural gas hydrate

Pressure in the deep-water pipeline is an important parameter that should be carefully predicted to control natural gas transport petroleum industry. However present methods predict pressure along are complex and time-consuming. Some even ignore formation of hydrate leading inaccurate prediction. In this work, we proposed a model considering reduction radius induced by hydrate. The was validated experimental data applied real China. Results indicate decline mainly caused due compared with flow resistance viscous flow. becomes faster against time 40% loss at fifth year transport. This enables obtain values high accuracy good convenience.
