In order to provide the basic data for the study on safe and economic operation under low throughput of Panjin pipeline,an experimental study on viscosity-temperature characteristics and rheological properties for crude oil of Panjin pipeline was carried out.The viscosity-temperature equation and the rheological equation for crude oil of Panjin pipeline were regressed.The viscosity-temperature curve and rheological curve at the different test temperature were drew.The results show that when the test temperature is at 50~80 ℃, the crude oil of Panjin pipeline shows Newtonian fluid behavior, and the regressed equation fits of the experimental data in higher degree.
