The physical properties of Gabon oil were characterized by analyzing paraffin content, pour point, viscosity, wax precipitation point, and yield value of six wells oil samples from Gabon A oilfield. All of the indicators are key points to the crude oil rheological properties. The results show that the crude oil of Gabon A oilfield is the crude oil containing high wax and high pour points. High carbon component accounts for a large portion of the paraffin components; paraffin content is above 34.04%, average pour point is 28.25℃, average wax precipitation point is 47.51℃, average yield value is 159.11Pa. For the oil samples of TST-B09H and NZOB-Z05H, the ratio of paraffin inhibition is over 90%, 80%, respectively by adding FLO-1 paraffin inhibitor of 100×10^-4. The data obtained provides a direct theoretical support for Gabonese crude oil extraction, transportation, processing, and for the on site work of wax prevention and cleaning of oil well, particularly for screening chemical agents for wax control.
