The Pressure Drop Calculation of Sea Water Pipe with No Heat Oil and Gas Transferring
This submarine pipeline was used to transport water originally, however, it is an oil-gas mixed transportation pipeline without heat preservation now. Because of the differences between the physical properties of oil-gas and water, we should take the gas and liquid viscosity, density and interfacial tension and other factors into account to establish a new submarine pipeline pressure drop model .In this passage, according to the field data provided by the 20B platform, 20A platform, 251B platform, cb502 platform of submarine pipeline, we apply the methods of comparative analysis and mathematical simulation to establish Beggs-Brill submarine pipeline pressure drop model and the temporary oil-free thermal insulation of the pressure drop and mathematical model, we also make the analysis of a variety of factors impacting on the pipeline pressure drop, including the starting temperature of media, gas liquid flow rates, pipe diameter, angle of inclination，Provide a reference basis to design submarine pipeline.
