| Abstract: | Abstract The viscosity of waxy crude oil and oils with different water contents from Bohai Sea oilfield with different temperature, pressure, and shear rate was studied. The relationship between viscosity and temperature or pressure fit well to the exponential law. The wax appearance temperature (WAT) at high pressure was also studied. The WAT increased linearly with pressure, and the slope was about 0.1°C/MPa. The maximum deviation of the WAT with different water contents was 0.5°C when the pressure changed from 0.1 to 12 MPa and this demonstrates that water content had little effect on the WAT of Bohai Sea crude oil. |
